(SEM II) THEORY EXAMINATION 2023-24 ENVIRONMENT AND ECOLOGY

This document contains the complete B.Tech (Semester II) Engineering Course Question Paper for Environment and Ecology, Subject Code BAS204, for the academic year 2023–24. The examination evaluates a student’s understanding of environmental systems, natural resources, pollution, climate change, population studies, and ecological balance. The paper is structured according to the university pattern and includes short, descriptive, analytical, and application-based questions.

The question paper is divided into three major sections:

SECTION A — Short Answer Questions (2 marks each)

This section contains seven concise questions that test basic environmental concepts. These include understanding types of environments, examples of natural resources, sustainable water usage, carbon cycles, greenhouse mechanisms, carbon monoxide toxicity, and agricultural practices like paddy straw burning. These questions check quick recall and conceptual clarity.

SECTION B — Medium-Length Analytical Questions (7 marks each)

Students must attempt any three questions. These cover deeper understanding of environmental threats, differences between natural and man-made environments, causes of air pollution such as AC usage, ozone depletion due to CFCs, and the issue of population explosion in India. This section focuses on reasoning, explanation, and environmental implications.

SECTION C — Detailed Descriptive Questions (7 marks each)

Students choose one question from each pair. These questions involve deeper analysis and structured explanation, including:

Environmental segments

Human impact on physical geography

Climate change effect on water resources

Global carbon cycle with diagrams

Water quality concerns in villages

Solid waste management categories

Acid rain formation and control

Greenhouse gases and global warming

Urbanization and industrial impacts

Environmental Impact Assessment (EIA) with flow chart

To provide a sense of the type and style of questions included, here are sample questions from the paper:

Sample Questions

“What is the sustainable use of water resources?” — tests understanding of conservation and responsible use of water.

“How is climate change affecting water resources? Explain.” — examines applied knowledge of global warming and hydrological impact.

These reflect the conceptual and analytical nature of the full examination paper.

Beyond these examples, the document contains many similar questions related to:

Pollution (air, water, soil, noise)

Global environmental threats

Resource management

Waste treatment

Carbon cycle and climate science

Greenhouse effect

Environmental policies and assessment

Impact of population growth and urbanization

This question paper provides a complete academic perspective of the Environment & Ecology syllabus, helping students understand the exam pattern, expected question formats, and critical topics essential for scoring well. The accompanying notes also include additional related questions, useful for further practice and exam preparation.
