Which of the following best describes the role of decomposers?

Decomposers play a crucial role in the ecosystem by breaking down dead organic matter into nutrients. This process is vital for the recycling of nutrients within an ecosystem. Decomposers, such as fungi and bacteria, decompose dead plants and animals, transforming complex organic materials back into simpler substances. This breakdown releases essential nutrients back into the soil, making them available for primary producers, such as plants.

Without decomposers, ecosystems would accumulate dead material, and nutrients would become locked in that organic matter, unavailable for use by plants and other organisms. Thus, decomposers contribute to nutrient cycling and support the overall health and productivity of the ecosystem. Their function ensures that energy and matter continue to flow within ecological communities, maintaining balance and sustainability.
