What is the role of decomposers in an ecosystem?

Decomposers play a crucial role in an ecosystem by breaking down dead and decaying organic matter, such as fallen leaves, dead plants, and animal remains. This process is essential for recycling nutrients back into the soil, making them available for producers like plants to utilize. Without decomposers, ecosystems would become overloaded with dead material, and the cycle of nutrient availability would be disrupted, ultimately affecting all levels of the food web. They help maintain the health of the environment by facilitating decomposition, which is critical for nutrient cycling and supporting the growth of autotrophic organisms. This interaction ensures the sustainability and balance of ecosystems.
