What role do decomposers play in an ecosystem?

• A. They produce energy through photosynthesis.
• B. They break down dead organic matter, recycling nutrients back into the ecosystem.
• C. They provide shelter for living organisms.
• D. They consume primary producers.

Answer: (B)

Decomposers play a critical role in ecosystems by breaking down dead organic matter, which includes fallen leaves, dead animals, and other organic materials. This process of decomposition is vital for nutrient cycling; as decomposers break down these materials, they convert them into simpler substances that can be absorbed by plants, thereby replenishing the soil with essential nutrients. Without decomposers, dead matter would accumulate, and nutrients would remain locked away, unavailable to living organisms. This recycling process ensures that ecosystems remain productive and sustain life over time. Thus, the contribution of decomposers is fundamental to ecosystem health and functionality by maintaining the balance of nutrients in the environment.
