What is one role of decomposers in ecosystems?

Decomposers play a crucial role in ecosystems by breaking down dead organic matter. This process is essential for nutrient cycling; when decomposers such as bacteria, fungi, and other microorganisms break down dead plants and animals, they release nutrients back into the soil. This nutrient recycling makes the nutrients available for uptake by living plants, which are primary producers in the ecosystem. By decomposing organic material, they help maintain soil health and fertility, which supports plant growth and ultimately sustains various forms of life within the ecosystem. This process also helps in the decomposition of waste materials and contributes to the overall energy flow in the ecosystem.
