Step 1: An ecosystem is a functional unit of nature consisting of both living organisms (biotic components) and their physical environment (abiotic components). These components interact with each other to maintain a balance and support life processes.
Step 2: The two main components of an ecosystem are:
1. Biotic Components: These are the living organisms within an ecosystem, including producers (plants), consumers (animals), and decomposers (fungi and bacteria).
2. Abiotic Components: These are the non-living factors that affect the ecosystem, such as sunlight, temperature, air, water, soil, and nutrients.
Step 3: The interaction between biotic and abiotic components forms the basis of ecological processes, such as nutrient cycling and energy flow. % Diagram to be inserted here.
