What role do decomposers play in an ecosystem?

Decomposers play a crucial role in ecosystems by breaking down dead organic material and recycling nutrients back into the environment. This process is essential for maintaining the health of ecosystems, as it ensures that nutrients are returned to the soil, making them available for plants to use. Decomposers, such as fungi and bacteria, decompose complex organic compounds found in dead plants and animals, converting them into simpler substances. This not only enriches the soil but also helps to sustain the cycle of life, supporting the growth of new organisms. Without decomposers, ecosystems would become overloaded with dead material, and nutrient recycling would be severely disrupted, leading to negative impacts on plant and animal life.
