What are decomposers? Give their role in the ecosystem.

(N/A) Decomposers are organisms that break down the complex organic matter found in dead remains of plants and animals into simpler inorganic substances.
Role of decomposers in the ecosystem:
$(i)$ They act as nature's scavengers by cleaning the environment through the decomposition of dead organic matter.
$(ii)$ They play a crucial role in nutrient cycling by releasing essential minerals back into the soil,which are then reused by producers (plants).
$(iii)$ They help in maintaining the balance of nutrients in the biosphere by converting complex organic compounds into a usable form.
