ANSWER: (C)
Explanation: Decomposers like bacteria and fungi break down dead plants, animals, and organic waste into simpler inorganic substances such as carbon dioxide, water, and minerals. These products are returned to the environment, where producers reuse them for photosynthesis and growth. Thus, decomposers recycle nutrients, clean the ecosystem of waste, and maintain the balance of nature.
