What is the primary role of decomposers in an ecosystem?

• A. To produce energy
• B. To consume other organisms
• C. To break down dead matter
• D. To compete for resources

Answer: (C)

Decomposers play a crucial role in ecosystems by breaking down dead organic matter, such as fallen leaves, dead plants, and animals. This process is essential for nutrient cycling, as decomposers convert complex organic materials into simpler substances, returning vital nutrients back to the soil. These nutrients are then available for plants to absorb and use for growth, which supports the entire ecosystem. By facilitating the breakdown of dead matter, decomposers also help to maintain the balance of ecosystems. Without them, waste would accumulate, and nutrients would become locked away in dead organisms, limiting the availability of essential elements for living organisms. This decomposition process ultimately supports the productivity and health of ecosystems, ensuring a continuous supply of energy and nutrients through the food web.
