Which term describes an organism that breaks down dead matter to recycle nutrients?

• A. Producers
• B. Consumers
• C. Autotrophs
• D. Decomposers

Answer: (D)

Breaking down dead matter to recycle nutrients is the job of decomposers. In ecosystems, when plants and animals die or produce waste, nutrients are locked up in those tissues. Decomposers such as fungi and bacteria break down that material, releasing minerals back into the soil, water, or air so other living things can reuse them. This recycling keeps nutrient cycles moving and supports new growth. Producers are organisms that make their own food, usually with sunlight, like plants. Autotrophs is another term for organisms that produce their own energy, not break down dead matter. Consumers obtain energy by eating other organisms, so they don’t primarily perform decomposition. That’s why decomposers are the best fit for describing an organism that breaks down dead matter to recycle nutrients.
