LIFE SCIENCE

Detailed explanation-1: -Nature has its own recycling system: a group of organisms called decomposers. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth’s cleanup crew.

Detailed explanation-2: -The two common examples of decomposers are bacteria and fungi. They play an important role in clearing the debris of dead remains of plants and animals and convert them into humus which enriches the nutrients of the soil.

Detailed explanation-3: -Decomposers play an important role in every ecosystem. Without decomposers, dead organisms would not be broken down and recycled into other living matter. The reason decomposers decompose, however, is simply because they need to survive.

Detailed explanation-4: -When plants die, they become food for decomposers like earthworms, bacteria and fungi. Decomposers or saprotrophs recycle dead organic bodies like plants into chemical nutrients like carbon and nitrogen that are released back into the air, soil and water. Bacteria and Fungi can be considered as plant decomposers.
