What are decomposers? What will be the consequence of their absence in an ecosystem?

The organisms which can decompose the dead plants and animals are known as decomposers. Bacteria and Fungi come under the category of decomposers. Decomposers plays an important role in environment by reducing the pressure on the ecosystem by cleaning the dead plants and animals. Moreover, they maintain the cycle by providing the raw material to the environment.

Absence of decomposers will lead to dead plants and animals accumulation in the nature only and environment would be without resources which are needed for survival of life.
