a) An ecosystem is a self - contained unit of living things (plants, animals, and decomposers), and their non -living environment (soil, air and water).
Ex:
♡A grassland
♡A forest
b) ¥Biotic components:
☆The Biotic components of an ecosystem is a community of organisms, which is made up of many different inter-dependent populations.
1. Producers-- which synthesize their own food. All the green plants are producers.
2. Consumers-- which are dependent on others for food. All animals are consumers.
3. Decomposers-- which consume the dead remains of other organisms. Certain bacteria and fungi are decomposers.
¥Abiotic components:
☆The abiotic components of an ecosystem include substances like carbon dioxide, nitrogen, oxygen, water, phosphorus, sulphur, sodium, potassium, calcium and other elements present in them.
☆The physical factors or climate factors like light, temperature, pressure and humidity are also considered abiotic components of the ecosystem.
