What role do decomposers play in an ecosystem?

Decomposers play a crucial role in an ecosystem by breaking down dead organisms and organic waste. This process is essential for nutrient cycling, as decomposers convert complex organic materials into simpler substances that can be reused by plants. By feeding on dead plants and animals, as well as waste products, they help to recycle nutrients back into the soil, making them available for autotrophs (like plants) to use for growth. This not only contributes to soil health but also ensures that energy flow within the ecosystem continues. Through their activities, decomposers help maintain the balance of ecosystems by facilitating the natural decomposition process, which prevents the accumulation of organic waste.
