Theory Examination (Semester-II) 2015-16 ENVIRONMENT & ECOLOGY

This is a 3-hour Theory Examination for Environment & Ecology (Semester–II), carrying 100 marks. The paper is divided into three sections – A, B, and C, and the student must attempt questions from all sections according to the instructions. The paper focuses on environmental issues, pollution, natural disasters, biodiversity, population studies, sustainable development, and ecological concepts.

Section – A (20 Marks)

Section A contains very short-answer questions, each testing basic environmental concepts. Students must answer all questions. Topics include:

sources and effects of noise pollution

the role of Central Pollution Control Board

the Nalgonda process and its uses

sustainable development

pollution from thermal power plants

population pyramids (pyramid, bell, urn shapes)

immigration and emigration

reasons for migration

This section checks quick recall and conceptual clarity.

Section – B (50 Marks)

Section B consists of descriptive questions, from which any five must be attempted. These questions require explanations, diagrams, and examples. Topics include:

types of biodiversity and threats to biodiversity

water pollution and its control methods

ozone layer formation, depletion, and role of CFCs

EIA (Environmental Impact Assessment), inventory, and monitoring

energy resources and examples

bioaccumulation and biomagnification

greenhouse gases: carbon dioxide, chlorofluorocarbons

blue baby syndrome

bio-indicators

migration and emigration

matching questions on environmental terms

This section checks understanding, reasoning, and the ability to express environmental processes clearly.

Section – C (30 Marks)

Section C contains three long-answer questions, out of which any two must be attempted. These questions require detailed descriptions, case studies, and proper explanations. Topics include:

sustainable development and how it can be achieved

case study of the Bhuj–Gujarat earthquake

explanation of landslides, causes, and effects

This section tests deeper knowledge, analytical ability, and descriptive writing.

Overall Summary

This question paper tests a student's understanding of environmental issues, ecological balance, natural disasters, pollution control, population studies, sustainability, and biodiversity.

Section A checks basic concepts

Section B focuses on detailed explanations
