Which of the following describes the primary role of decomposers in an ecosystem?

The primary role of decomposers in an ecosystem is to break down dead organisms and recycle nutrients. Decomposers, which include organisms like bacteria and fungi, are essential for the nutrient cycle. When plants and animals die, decomposers facilitate the breakdown of their complex organic materials into simpler substances. This process releases nutrients such as nitrogen and phosphorus back into the soil, making them available for uptake by plants. In doing so, decomposers play a crucial role in maintaining ecosystem health and productivity by ensuring that essential nutrients are continuously recycled, thereby sustaining life. This function also helps in the decomposition process, which avoids the accumulation of dead matter in the environment.
