What is the primary function of decomposers in an ecosystem?

The primary function of decomposers in an ecosystem is to recycle nutrients back into the soil. Decomposers, which include microorganisms such as bacteria and fungi, play a crucial role in breaking down dead organic matter, including plant and animal remains. As they decompose this material, they release essential nutrients like nitrogen, phosphorus, and potassium back into the soil, making them available for plants to absorb. This process is vital for nutrient cycling and maintaining soil fertility, ultimately supporting the growth of new plants and sustaining the entire ecosystem.

Decomposers are essential for the stability and productivity of ecosystems, as they ensure that nutrients are not lost but rather continuously returned to the soil. By facilitating this cycle, decomposers help promote biodiversity and the overall health of the environment.
