environment and ecology study guide
This page collects every Environment and Ecology resource on AcademicArk for AKTU first-year (Semester 1 and 2) students: 13 PDFs in total, including 8 typed notes sets and 5 previous year question papers. Each resource opens with a preview, and the list is ordered by what students have recommended, downloaded and viewed most.
The EVS syllabus is divided into 5 units: Unit 1 (Environment and Ecosystem), Unit 2 (Natural Resources), Unit 3 (Environmental Pollution), Unit 4 (Current Environmental Issues) and Unit 5 (Environmental Protection).
AcademicArk has analysed 6 AKTU EVS question papers from 2023 to 2026, covering 154 questions. Unit 1 (Environment and Ecosystem) carries about 27 marks per paper, while Unit 2 (Natural Resources) carries about 24 marks per paper. The most repeated topics are Environment Definition and Types (asked 12 times), Ecosystem Structure and Types (asked 12 times), Global Warming and Climate Change (asked 12 times) and Water Pollution (asked 11 times). The full unit-wise breakdown, important questions and a predicted paper are linked in the exam intelligence card on this page.
EVS answers are descriptive, so structure matters: definition, types or causes, effects, control measures and an example. Pollution types and their control, biodiversity hotspots and conservation, and food chains and energy flow are asked in most years. A labelled diagram (energy pyramid, nitrogen cycle) adds easy marks.

Which EVS topics are asked most?
Pollution and its control, ecosystems and energy flow, biodiversity and conservation, and global environmental issues appear in most papers.
How should I write EVS answers?
Use headings: definition, causes, effects, control measures and an example. Add a simple labelled diagram wherever possible.
How many EVS previous year papers has AcademicArk analysed?
6 AKTU Environment and Ecology papers from 2023 to 2026, with 154 questions mapped to units and topics, so you can see exactly what repeats before the exam.
Which unit of EVS is most important for the AKTU exam?
Based on previous year papers, Unit 1 (Environment and Ecosystem) carries the most weight at about 27 marks per paper. The topics that repeat most are Environment Definition and Types, Ecosystem Structure and Types and Global Warming and Climate Change.
