What role do decomposers play in nutrient cycling?

Decomposers play a crucial role in nutrient cycling by breaking down dead organic matter, such as fallen leaves, dead plants, and animal remains. Through their metabolic processes, they convert this organic matter into simpler inorganic compounds. This breakdown releases essential nutrients, such as nitrogen, phosphorus, and potassium, back into the soil. These nutrients are then available for uptake by plants, which are foundational to the food web. Consequently, decomposers are key players in maintaining the health of ecosystems by ensuring that nutrients are continuously recycled, supporting plant growth and overall ecosystem productivity. Their activity contributes to soil fertility and plays a vital role in sustaining life on Earth.
