Question

Conversion of nitrogen-containing organic molecules into nitrates is done by

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

Answer 1

The correct option is A Decomposers.

Once the animal or the plant dies, other bacteria in the soil convert the various compounds of nitrogen back into nitrates and nitrites. A different type of bacteria converts the nitrates and nitrites into elemental nitrogen.

These bacteria are the decomposers.

Thus, the correct option is A.
