EVERYDAY SCIENCE

Detailed explanation-1: -They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes. Fungi are important decomposers, especially in forests.

Detailed explanation-2: -Decomposers act on the dead matter, e.g. by secreting the enzymes and digesting the matter externally. Saprotrophs contribute to the decomposition process by extracellular digestion, i.e., they digest dead matter externally by secreting enzymes and then absorbing the nutrients.

Detailed explanation-3: -Decomposers are also called saptrotrophs. They show saprotrophic mode of nutrition i.e. they feed on dead and decaying matters. For example, bacteria, fungi, etc. Autotrophs are producers which include plants. Phagotrophs or heterotrophs are consumers who depend on plants and animals for their nutrition.

Detailed explanation-4: -When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.
