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

Decomposers play a crucial role in ecosystems by breaking down dead organic matter and recycling nutrients back into the environment. This process is essential for maintaining the health of ecosystems, as it facilitates the return of valuable nutrients, such as carbon, nitrogen, and phosphorus, into the soil, making them available for uptake by plants.

Without decomposers, organic material would accumulate, and nutrients would remain locked in decaying matter, leading to a decline in soil fertility and affecting plant growth. This recycling process supports the entire food web, as plants (primary producers) rely on these nutrients to thrive, ultimately supporting herbivores and higher trophic levels. Thus, the activity of decomposers ensures the continuity and stability of ecosystems, allowing energy flow and nutrient cycling to occur effectively.
