Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Detailed explanation-2: -Fungi like mushrooms, mildew, mold and toadstools are not plants. They don’t have chlorophyll so they can’t make their own food. Fungi release enzymes that decompose dead plants and animals.
Detailed explanation-3: -The decomposers complete the cycle by returning essential molecules to the plant producers. Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds.
Detailed explanation-4: -Different decomposers Fungi release chemicals to break down dead plants or animals into simple substances. They absorb some of these substances for growth, but others enter the soil. Earthworms digest rotting plant and animal matter as they swallow soil.
Detailed explanation-5: -Decomposers decompose the carcasses of dead animals and derive food needs from them. Decomposers are organisms that act on dead plants and animals to turn them into dark-colored substances called humus.
