What is the role of decomposers in an ecosystem?

The role of decomposers in an ecosystem is crucial as they break down dead organic matter and recycle nutrients back into the soil. This process is essential for maintaining the health of the ecosystem because it allows nutrients to be reused by plants, which are the primary producers. By decomposing organic materials, such as fallen leaves, dead animals, and other organic waste, decomposers like fungi and bacteria convert these materials into simpler substances. This not only enriches the soil but also ensures that essential nutrients are available for the growth of new plants, thus supporting the entire food web. Without decomposers, ecosystems would become overloaded with dead material, leading to a depletion of nutrients and ultimately affecting the survival of various organisms within the ecosystem.
