BANC 106 Solved Question Paper June 2026 is our complete answer file for the official IGNOU term-end paper of Human Ecology: Biological and Cultural Dimensions, a core course of the B.Sc. (Honours) Anthropology programme. It answers all 9 questions printed in the June 2026 paper, across Sections A, B and C.
1. What the June 2026 Solved Paper Includes
We started from the actual BANC 106 question paper for June 2026, not from a list of guessed topics. Our subject experts then wrote each answer at the length the paper itself asks for: about 400 words for a 20-mark question and about 200 words for a 10-mark note. The aim is simple. You should be able to read an answer once and reproduce its structure in the exam hall.
Before writing, we read earlier BANC 106 papers so that each answer also shows you what keeps coming back. Allen's rule, cultural ecology and the scope of ecology are not one-off topics in this course; they have returned in most sittings since December 2021. The answers lean on those repeat areas with named scholars and dates, which is what separates a pass from a strong score.
Two answers are printed in full just below so you can judge the writing. The other seven stay in the paid file, and the full set is shared on WhatsApp at 9899436384.
2. Two Answers Solved in Full, Seven Held Back
Q1 and Q2 from Section A of the June 2026 BANC 106 paper are answered in full below, with the question text exactly as printed and the paper's own numbering. Read them as proof of how every answer in the full file is built.
Concept of ecology and its scope
Question 1: Explain the concept of ecology and analyse its scope in understanding environmental relationships. (20)
Introduction. Ecology is the scientific study of the relationships between living organisms and their environment. The German zoologist Ernst Haeckel coined the term in 1866 from the Greek words oikos, meaning house or dwelling place, and logos, meaning study. E.P. Odum later described ecology as the study of the structure and function of nature.
Concept of ecology
- Organism and environment: no organism lives alone. Its environment has abiotic parts such as light, temperature, water, soil and air, and biotic parts such as plants, animals and micro-organisms.
- Levels of organisation: ecology works from the individual to the population, community, ecosystem, biome and finally the biosphere.
- Two branches: autecology studies a single species and its environment, while synecology studies groups of species living together as communities.
- Ecosystem: A.G. Tansley introduced the term in 1935 for a biotic community and its abiotic environment functioning together as one unit.
Scope in understanding environmental relationships
- Habitat and limiting factors: ecology explains why an organism lives where it does. Liebig's law of the minimum (1840) shows that growth is controlled by the scarcest necessary factor.
- Energy flow: it traces energy from producers to herbivores, carnivores and decomposers. Lindeman's trophic-dynamic study (1942) showed that only a small part of energy passes from one level to the next.
- Interactions between species: ecology explains predation, competition, mutualism and parasitism, the relationships through which one species limits or supports another in the same habitat.
- Nutrient cycles: carbon, nitrogen and water cycles explain how matter is reused between living and non-living parts of nature.
- Population ecology: density, birth rate, death rate and growth patterns explain why populations rise, stabilise or crash.
- Community ecology and succession: it shows how communities change over time, from pioneer species to a relatively stable climax community.
- Applied ecology: conservation of forests and wildlife, control of pollution, management of agriculture and fisheries, and planning for climate change all rest on ecological knowledge.
- Human ecology: for anthropology, the most important scope is the study of how human groups adapt biologically and culturally to their surroundings, which is the core of BANC 106.
Conclusion. Ecology is not only a branch of biology but a way of seeing every organism, including human beings, as part of a network of relationships. Its scope runs from single habitats to the whole biosphere, and it gives the basic concepts on which human ecology and anthropology build.
Human ecology and its relationship to other sciences
Question 2: Examine the relationship of human ecology to other sciences, evaluating its interdisciplinary significance. (20)
Introduction. Human ecology studies the interrelationships between human populations and their natural, social and built environments. Sociologists Robert E. Park and Ernest W. Burgess used the term in 1921, and geographer Harlan H. Barrows described geography itself as human ecology in 1922. Because people are both biological and cultural beings, human ecology has to borrow from many sciences.
Relationship with other sciences
- Biology and general ecology: human ecology takes its core ideas of population, niche, ecosystem, adaptation and natural selection from biology. Bergmann's rule (1847) and Allen's rule (1877) are applied to explain human body size and limb proportions.
- Physiology and human biology: studies of acclimatisation to heat, cold and high altitude, and of growth and nutrition, come directly from physiology.
- Anthropology: Julian Steward developed cultural ecology in Theory of Culture Change (1955), and Roy Rappaport's Pigs for the Ancestors (1968) showed ritual regulating the ecology of the Tsembaga Maring of New Guinea.
- Sociology: the Chicago School applied ecological ideas to cities, and Burgess's concentric zone model (1925) explained how urban groups sort themselves into zones.
- Geography: the debate between environmental determinism, linked with Friedrich Ratzel, and possibilism, linked with Vidal de la Blache, is shared by human ecology and geography.
- Medicine and epidemiology: disease ecology explains patterns such as the high frequency of the sickle-cell trait in malarial regions of Africa.
- Demography and economics: population size, carrying capacity and resource use connect human ecology with Malthus's essay on population (1798) and modern resource economics.
Interdisciplinary significance
- Holistic view: no single science explains why a community lives, eats and falls ill the way it does; human ecology joins the biological and cultural sides.
- Mixed methods: it combines body measurement and health data with fieldwork, interviews and surveys.
- Practical use: it guides public health, urban planning, disaster response and community-based conservation.
- Development and policy: it helps judge how dams, mining or displacement change the lives of forest and tribal communities, a long-standing concern of Indian anthropology.
- Limits: its wide boundaries can make it loose, and early urban ecology was criticised for treating cities too much like plant communities.
Conclusion. Human ecology is a meeting point of the natural and social sciences. Its value lies in combining their tools to explain human adaptation as a whole, and that interdisciplinary character is exactly what makes it central to anthropology.
3. Questions Answered Only in the Full File
The seven questions below are listed exactly as printed, so you know what the file contains. Their answers are in the full file only.
Question 3 (Section A): Outline the key characteristics of a population in the context of population ecology. (20)
Question 4 (Section A): Write short notes on any two of the following. (10 + 10)
(a) Cultural ecology and anthropology
(b) Impact of urbanization and industrialization on human adaptation
(c) Structural point of view of ecosystem
Question 5 (Section B): Discuss how humans adapt to various climatic zones. (20)
Question 6 (Section B): Contrast the adaptation strategies for infectious and non-infectious diseases across different geographical regions of the world. (20)
Question 7 (Section B): Explore the dynamics of cultural dimensions within agricultural and peasant ecology. (20)
Question 8 (Section B): Write short notes on any two of the following. (10 + 10)
(a) Environmental possibilism
(b) Horticultural societies
(c) Allen's rule in ecology
Question 9 (Section C, compulsory): Discuss the various steps involved in developing a concise research synopsis. (20)
Section B and Section C carry 60 of the 100 marks, and none of those answers appears on this page. Q9 alone is worth 20 compulsory marks, and in our reading it is the question students most often leave half-done.
4. Syllabus by Block and Unit
BANC 106 is taught in 3 blocks and 11 units, with research methods kept in a separate Practical Manual. Block 1 builds the basic ideas of ecology and human ecology, Block 2 deals with biological adaptation, and Block 3 with the cultural side of human ecology.
| Block | Unit | Unit title | Topics this unit is known for |
|---|---|---|---|
| Block 1: Fundamentals of Human Ecology | Unit 1 | Basic Concepts of Ecology | Tansley's ecosystem of 1935, autecology and synecology, structural and functional view of the ecosystem |
| Block 1: Fundamentals of Human Ecology | Unit 2 | Understanding Human Ecology | Meaning and scope of human ecology, its links with morphology, physiology and other sciences |
| Block 1: Fundamentals of Human Ecology | Unit 3 | Anthropology and Human Ecology | Cultural ecology as a sub-field, Julian Steward's culture core, ethnocentrism against cultural relativism |
| Block 1: Fundamentals of Human Ecology | Unit 4 | Methods of Studying Human Ecology | Comparative method, cause and effect method, multiple stress and strain relationships |
| Block 2: Biological Dimensions of Human Ecology | Unit 5 | Adaptation to Various Ecological Zones | Acclimation and acclimatisation, heat and cold stress, high-altitude hypoxia |
| Block 2: Biological Dimensions of Human Ecology | Unit 6 | Influence of Environmental Factors | Factors in growth and development, effects of radiation and noise pollution, nutritional stress |

The official unit texts are on the eGyanKosh BSCANH Semester-III page, which lists BANC-106 and its Practical Manual together.
If you want the unit-wise notes rather than exam answers, the BANC 106 Study Material page is the better starting point; this file is the answer layer on top of it.
5. Paper Pattern and Marks Split
The June 2026 BANC 106 paper had 9 questions for 100 marks in 3 hours: attempt any two from Section A, any two from Section B, and the single Section C question, which is compulsory.
| Section | Questions printed | To attempt | Marks | June 2026 focus |
|---|---|---|---|---|
| Section A | Q1 to Q4 | Any two | 40 | Ecology, human ecology and allied sciences, population ecology |
| Section B | Q5 to Q8 | Any two | 40 | Climatic and disease adaptation, peasant ecology, Allen's rule |
| Section C | Q9 | Compulsory | 20 | Steps in developing a concise research synopsis |
One change is worth noticing. In June 2024 Section C was split into two 10-mark parts, and in December 2025 it carried two separate 10-mark items. In June 2026 it became a single 20-mark question on the research synopsis. A student who had prepared only two short notes would have found that answer thin.
If you are comparing papers across the whole programme, the BSCANH Question Paper collection places this paper beside the other Semester III anthropology courses.
6. Topics IGNOU Keeps Repeating in BANC 106
Six official BANC 106 papers were read for this table: December 2021, June 2022, December 2022, June 2024, December 2025 and June 2026. Each June 2026 question is matched with the earlier sittings where the same topic appeared. We did not locate the June 2023, December 2023, December 2024 and June 2025 papers, so they are not counted.
| June 2026 question | Topic | Sittings where it appeared | Count (of 6) |
|---|---|---|---|
| Q1 (Sample 1) | Concept and scope of ecology and human ecology | Dec 2021, Jun 2022, Dec 2022, Dec 2025, Jun 2026 | 5 |
| Q3 | Population ecology and population density | Dec 2021, Dec 2022, Jun 2024, Dec 2025, Jun 2026 | 5 |
| Q4(a) | Cultural ecology and human ecology in anthropology | Dec 2021, Jun 2022, Dec 2022, Jun 2024, Jun 2026 | 5 |
| Q8(c) | Ecological rules, including Allen's rule | Dec 2021, Jun 2022, Dec 2022, Jun 2024, Jun 2026 | 5 |
| Q6 | Ecology of infectious and other diseases | Dec 2021, Jun 2022, Jun 2024, Jun 2026 | 4 |
| Q8(b) | Horticulture, hunting-gathering and other pre-industrial modes | Dec 2021, Jun 2022, Dec 2025, Jun 2026 | 4 |
| Q9 | Research synopsis or research proposal | Jun 2022, Jun 2024, Dec 2025, Jun 2026 | 4 |
| Q4(b) | Urbanisation, industrialisation and industrial civilisation | Jun 2022, Dec 2022, Jun 2026 | 3 |
| Q5 | Adaptation to climate and high altitude | Dec 2021, Jun 2024, Jun 2026 | 3 |
| Q7 | Cultural dimensions of agricultural and peasant ecology | Jun 2022, Dec 2025, Jun 2026 | 3 |
| Q8(a) | Possibilism and man-environment theories | Jun 2024, Dec 2025, Jun 2026 | 3 |
| Q2 (Sample 2) | Human ecology and other sciences | Jun 2024, Jun 2026 | 2 |
| Q4(c) | Ecosystem and its structural view | Jun 2024, Jun 2026 | 2 |
The pattern is easy to read. Four of these topic areas reached five sittings out of six, and Q7 in June 2026 repeats the June 2022 wording almost word for word. Cultural materialism is the odd one out: it appeared in four earlier papers but skipped June 2026, which makes it a strong topic to keep ready for December 2026.
You can open the earlier papers yourself through our IGNOU Previous Year Question Paper section and check each row against the originals.
7. How Our Answers Are Written and Checked
Every BANC 106 answer is drafted from the IGNOU study material for Blocks 1 to 3 and the Practical Manual, then checked against the wording of past papers before it goes into the file. That is why the answers in this file read like exam answers and not like textbook summaries.
Each answer follows the same four steps. A one-line definition with a named scholar opens it. Headed or numbered points carry the body, because examiners mark points. A dated example, such as Tansley 1935 or Rappaport 1968, anchors the argument. A two-line conclusion closes it.
For papers that have not been set yet, we prepare topic-based files instead; the IGNOU Solved Guess Paper range covers BANC 106 and the other BSCANH courses on that basis.
One honest limit applies: this is an aid to the official blocks, not a replacement for them.
8. Solved File Index and Practical Manual Questions
All 9 questions of the June 2026 BANC 106 paper are listed below with their course unit and where the answer sits: 2 on this page and 7 in the full file only. Section C comes from the BANC-106 Practical Manual, so a second table shows every Section C question set in the official papers we read.

| Q8 | B | Possibilism; horticultural societies; Allen's rule | 10 + 10 | Block 2, Unit 8; Block 3, Units 9 and 10 | Full file |
| Q9 | C | Steps in a concise research synopsis | 20 | BANC-106 Practical Manual | Full file |
| Session | Section C question | Practical Manual area |
|---|---|---|
| December 2021 | Preparation of fieldwork; tools and techniques in anthropology | Planning fieldwork and choosing tools |
| June 2022 | Research methods in human ecology; preparation of research synopsis | Methods and synopsis format |
| December 2022 | Tools and techniques of data collection; data analysis | Data collection and analysis |
| June 2024 | Fieldwork; preparation of a research synopsis | Field entry and synopsis writing |
| December 2025 | Sample research proposal on any topic; types of research methods in anthropology | Proposal drafting and method types |
| June 2026 | Steps involved in developing a concise research synopsis (single 20-mark question) | Synopsis steps from topic to references |
The synopsis or proposal has now been asked in four of these six sittings. That is why the Q9 answer in the full file is written as a clear sequence you can reuse for any synopsis question, and why it is worth practising before the exam.
9. Programmes That Include BANC 106
BANC 106 is a 6-credit core course of the IGNOU B.Sc. (Honours) Anthropology programme and sits in Semester III on eGyanKosh. Learners of the IGNOU Bachelor of Science (Honours) Anthropology (BSCANH) study it alongside BANC-105 Tribes and Peasants in India and BANC-107 Biological Diversity in Human Population.
If you are taking BANC 105 or BANC 107 in the same sitting, ask for them together when you message us, since the three Semester III papers share ideas on adaptation and peasant life.
10. How to Get the Full Solved Question Paper
Send a WhatsApp message to 9899436384 with the words BANC 106 June 2026 and we will share the full file with all 9 answers. That is the 2 answers you have already read plus the 7 answered only in the file, including the 20-mark Section C synopsis question.
The file is shared as a PDF. Price and delivery are confirmed in the same chat before anything is sent, so there is nothing to sign up for on this page. Mention whether you are preparing for December 2026 or a later sitting, and we will say which repeat topics to add.
11. BANC 106 Human Ecology FAQs
These are the questions BANC 106 students ask us most often, each answered in a few lines.
How do I get the full solved paper on WhatsApp, and how many answers does it contain?
Send a message to 9899436384 on WhatsApp with the words BANC 106 June 2026. The full file answers all 9 questions of the official paper, which means the 2 answers shown on this page plus the 7 that are available only in the file. Price, format and delivery are confirmed in the same chat before anything is sent to you, so there is no form to fill in.
Which BANC 106 questions are solved in full on this page?
Two questions are solved in full on this page: Q1 on the concept and scope of ecology, and Q2 on the relationship of human ecology with other sciences. Both come from Section A of the June 2026 BANC 106 paper. The remaining seven questions are listed on this page as question text only, and their answers sit in the full file.
What is the exam pattern of the BANC 106 paper?
The BANC 106 paper carries 100 marks and runs for 3 hours. It has three sections: you attempt any two questions from Section A, any two from Section B, and the single Section C question is compulsory. In June 2026 there were 9 questions in all, and the printed word limits were 400 words for 20 marks and 200 words for 10 marks.
Which BANC 106 topics repeat most often?
Across the six official papers we read, from December 2021 to June 2026, three topics came up five times each: the concept and scope of ecology, cultural ecology in anthropology, and the ecological rules including Allen's rule. Population ecology also appeared five times if the December 2025 question on population density is counted. Research synopsis or proposal writing appeared in four Section C papers.
Is Section C of BANC 106 taken from the Practical Manual?
Yes, in practice. Section C of BANC 106 has asked about fieldwork, data collection, research methods and research synopsis or proposal writing in every paper we checked, and these topics sit in the separate BANC-106 Practical Manual on eGyanKosh rather than in Blocks 1 to 3. In June 2026 Section C was one compulsory 20-mark question on the steps of a concise research synopsis.
Which programme and semester include BANC 106?
BANC 106 Human Ecology: Biological and Cultural Dimensions is a 6-credit core course of the IGNOU B.Sc. (Honours) Anthropology programme, BSCANH, and eGyanKosh lists it under Semester III. In the same semester, BSCANH learners also study BANC-105 Tribes and Peasants in India and BANC-107 Biological Diversity in Human Population, which is why we often prepare all three together.
How long should BANC 106 answers be in the term-end exam?
The BANC 106 paper prints its own limits: about 400 words for a 20-mark question and about 200 words for a 10-mark short note. Our answers follow those limits closely. Writing far beyond them rarely adds marks and it eats into the time you need for the other answers, which matters in a three-hour paper where you write five answers in all.
Is the June 2026 solved paper useful for the December 2026 exam?
Yes, it is useful for December 2026 revision, because the BANC 106 paper repeats its core topics heavily between sittings. Topics such as ecological rules, cultural ecology and population ecology have returned again and again. That said, no one can promise which questions will be set next, so treat the file as a guide to the syllabus and not as a prediction.
