Which type of organism is primarily responsible for recycling nutrients in ecosystems?

• A. Producers
• B. Primary consumers
• C. Decomposers
• D. Tertiary consumers

Answer: (C)

Decomposers play a vital role in recycling nutrients within ecosystems by breaking down dead organic matter and waste products. This process involves the breakdown of complex organic substances into simpler forms, which are then made available to producers, such as plants, in the soil. Decomposers, which include fungi, bacteria, and certain insects, carry out essential functions that maintain the balance of ecosystems by facilitating nutrient cycling. As they decompose material, they release nutrients back into the soil, which allows producers to absorb these nutrients and continue the cycle of life, thus supporting the entire food web. Their activity ensures that nutrients are not lost but rather recycled for use by various organisms within the ecosystem.
