Which organisms recycle nutrients back to the soil?

Which organisms recycle nutrients back to the soil?

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

Answer: (B)

Nutrient cycling through ecosystems depends on decomposers breaking down dead material and waste to release nutrients back into the soil. Decomposers like bacteria and fungi use enzymes to break down complex organic substances from dead plants and animals, returning inorganic forms such as ammonium, nitrates, and phosphates to the soil. This recycling makes nutrients available again for plants to take up and reuse, sustaining the whole system. Producers and autotrophs mainly start with nutrients from the soil and convert light energy into organic matter, while consumers eat other organisms and contribute waste but don’t perform the crucial recycling step. So, decomposers are the ones that return nutrients to the soil, completing the cycle.
