What is the role of decomposers in an ecosystem?

Decomposers play a crucial role in ecosystems by breaking down dead organic matter, such as fallen leaves, dead animals, and other waste products. This process of decomposition transforms complex organic materials into simpler substances, which are then released into the soil. Through this action, decomposers recycle essential nutrients like nitrogen, phosphorus, and potassium back into the environment. This nutrient recycling is vital because it helps maintain soil fertility and provides the necessary nutrients for plants (producers) to grow. Healthy plant growth, in turn, supports herbivores and, ultimately, the entire food web. Therefore, the role of decomposers is foundational for sustaining ecosystem balance and productivity.
