Which of the following describes the main function of decomposers in an ecosystem?

Decomposers play a crucial role in ecosystems by breaking down organic matter from dead plants, animals, and waste products. This process not only helps in the decomposition but also recycles nutrients back into the soil, making them available for use by autotrophs, or producers. By breaking down complex organic materials, decomposers convert them into simpler substances that can be taken up by plants, thus contributing to nutrient cycling. This recycling of nutrients is essential for maintaining the health of ecosystems, as it ensures that essential elements like nitrogen and phosphorus are returned to the soil, supporting continued plant growth and productivity. Without decomposers, ecosystems would accumulate dead material, and the essential nutrients would become locked away, unaccessible to living organisms.
