Following is the role of a decomposer in the ecosystem: They act as a cleansing agent of the environment by decomposing the dead plants and animals. (4) 6. Decomposers are organisms that break down the organic matter in the dead bodies of plants and animals and return them to the environment. What is the reason for Okazaki fragments being formed during DNA replication? Fungi are particularly suited to penetrating large pieces of decaying matter like wood with their hyphae and breaking it down with lignin-digesting enzymes. Decomposers: Decomposers include organisms like fungi and many species of bacteria. Fungi as decomposers: Fungi are an important part of ecosystem nutrient cycles. Why are smaller food chains better? We use DHL or FEDEX to ensure fast Delivery. They create the matter, or biomass, that sustains the rest of the ecosystem. This is the constant process of ingesting, excreting and recycling that goes on in an ecosystem. Mention three information obtained from the energy flow diagram. Organisms in this level of the food chain provide nutrients for the producers (plants) who in turn are eaten by the consumers in the next level who are then eaten by tertiary consumers. The main reason that decomposers are so important to an ecosystem is because of their role in recycling nutrients back into the environment. The food chain starts from the base, which consists of producer organism and moves up the series in a straight line. Energy flow in a food chain is unidirectional. [Delhi] Answer. When decomposers break down dead bodies and waste, they make it possible for the atoms in them to be reused by other organisms. Decomposers are very important for any ecosystem. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? They receive their nutrients through their hyphae, which invade and decay the tree trunk. Also refer to the link, here . It prevents foul smell and checks spread of disease.
