Returning elements to the environment so they can be reused is known as what?

• A. Nutrient recycling
• B. Decomposition
• C. Biomagnification
• D. Leaching

Answer: (A)

Nutrient recycling is the process by which elements are returned to the environment after use so they can be reused by living organisms. In ecosystems, nutrients cycle between organisms and their surroundings. When organisms die or produce waste, decomposers such as bacteria and fungi break down the organic matter and release minerals back into soil, water, or air. Plants and other producers can then take up these minerals again, continuing the cycle. This broader idea includes decomposition as a key step, but focuses on the ongoing return and reuse of nutrients rather than just the breaking down itself. By contrast, leaching involves nutrients being washed away from the soil and lost from the system, while biomagnification refers to the buildup of certain substances up the food chain.
