What are the important topics in NVS PGT Biology Ecology?

Dear Students,

As you prepare for the NVS PGT Biology examination, it’s essential to focus on key topics within Ecology. Here are the important areas you should concentrate on:

1. Ecosystem Dynamics
   • Structure and function of ecosystems
   • Energy flow and trophic levels
   • Biogeochemical cycles (carbon, nitrogen, phosphorus)
2. Population Ecology
   • Population growth models (exponential and logistic)
   • Factors affecting population size
   • Concepts of carrying capacity and ecological niches
3. Community Ecology
   • Species interactions (predation, competition, mutualism, commensalism)
   • Succession (primary and secondary)
   • Biodiversity and its significance
4. Conservation Biology
   • Threats to biodiversity (habitat destruction, pollution, climate change)
   • Conservation strategies and protected areas
   • Endangered species and extinction
5. Human Impact on Ecosystems
   • Environmental issues (deforestation, urbanization)
   • Sustainable development practices
   • Role of biotechnology in conservation

To excel in these areas, consider the following study strategies:

• Regular Revision: Schedule consistent revision sessions to reinforce your understanding.
• Practical Applications: Engage in field studies or virtual labs to observe ecological principles firsthand.
• Mock Tests: Practice with previous years’ question papers to familiarize yourself with exam patterns.
