What happens to nutrients after decomposers break down dead material?

• A. They are returned to the soil and reused by plants.
• B. They are carried away by wind.
• C. They evaporate into the air.
• D. They remain in the dead material.

Answer: (A)

When dead material breaks down, nutrients are released back into the environment through decomposition. Decomposers such as bacteria and fungi digest the remains and convert them into simpler nutrients—like minerals and nitrogen compounds—that dissolve in the soil water. Plant roots can then absorb these nutrients, so the soil gets replenished and can support new plant growth. This recycling keeps nutrients in the ecosystem and makes them available for reuse by plants and other organisms. Choices about nutrients being blown away by wind or evaporating don’t reflect how decomposition feeds plants; most nutrients are returned to the soil rather than lost to the air or empty space in the dead material.
