Question

Name various biotic factors in an ecosystem. Explain their significance.

Answer 1

Biotic factors are the living components: producers (plants and algae), consumers (herbivores, carnivores and omnivores) and decomposers (mainly bacteria and fungi).

Significance:

1. Producers: Green plants prepare food through photosynthesis and form the base of food chains.
2. Consumers: Herbivores, carnivores and omnivores obtain food from other organisms and help in energy transfer.
3. Decomposers: Bacteria and fungi decompose dead organisms and organic wastes, recycling nutrients into the ecosystem.
