What is an ecosystem? List its two main components. We do not clean natural ponds or lakes, but an aquarium needs to be cleaned regularly. Why is it so? Explain.
Answer:
- An ecosystem is made up of plants, animals and microorganisms living in an area together with non living components like climate, soil, rivers etc
- Two main components of an ecosystem are
- Biotic components
- Abiotic components
- An aquarium is not a natural ecosystem, it is man-made and hence it is not self sufficient. We need to clean an aquarium because of the absence of natural decomposers and also because the water in an aquarium is stagnant.
