Explanation:
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: -Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.
Detailed explanation-3: -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.
