Question

_____ return nutrients to the soil for plants to use, so they are also called nutrient recyclers.

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

Answer 1

The correct option is D Decomposers

Decomposers feed on wastes, debris of plants and animals, or on their dead remains after they die. When they feed on these nutrients, they convert the complex organic substances into simple inorganic substances and release them in the soil. These inorganic substances are taken up by plants and that can again be taken up by animals, creating a cycle. Hence, the decomposers are also known as recyclers.
