Class 12 Biology - Chapter 12: Ecosystem
Explore the structure and functioning of ecosystems in Class 12 Biology Chapter 12. Learn about energy flow, food webs, nutrient cycles, and ecological succession.
Overview
This chapter explains the structure and function of ecosystems. It covers components of ecosystems, energy flow, food chains and webs, ecological pyramids, productivity, nutrient cycling, and ecological succession.
Why This Chapter Matters
Ecosystems form the foundation of environmental biology. Understanding their dynamics helps in conserving biodiversity and managing natural resources sustainably.
Real-Life Applications
- Understanding how energy flows and nutrients cycle through ecosystems.
- Analyzing ecological pyramids and food webs.
- Exploring processes like primary and secondary succession in nature.
Skills You Will Learn
- Drawing and interpreting food chains, pyramids, and cycles.
- Differentiating between types of productivity (GPP, NPP).
- Understanding the role of decomposers and the stability of ecosystems.

Q: What is the difference between GPP and NPP?
A: Gross Primary Productivity (GPP) is the total energy captured by producers, while Net Primary Productivity (NPP) is the energy left after respiration.

Q: What is ecological succession?
A: Ecological succession is the natural, gradual process by which ecosystems change and develop over time.
