NEET BIOLOGY

Detailed explanation-1: -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. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere.

Detailed explanation-2: -A decomposer is an organism that feeds on and breaks down dead plant or animal matter, making organic nutrients available to the ecosystem. Often a decomposer is a bacterium, fungus, or invertebrate. Decomposers play a critical role in the flow of energy through an ecosystem.

Detailed explanation-3: -Decomposers are bacteria and fungi which break down dead plant and animal matter. They secrete enzymes on the surface of the dead organisms to break them down and then absorb the digested, smaller food molecules.

Detailed explanation-4: -Fungi decompose organic matter by releasing enzymes to break down the decaying material, after which they absorb the nutrients in the decaying material.

Detailed explanation-5: -Bacteria and fungi are called decomposer because they break down the dead and decaying organic matter into a simpler substance. It provides the nutrients back to the soil.
