• B. Formation of nitrates from ammonia.
• C. Formation of ammonia from nitrates.
• D. Release of free nitrogen back into the atmosphere.

Answer 1

The correct option is C Formation of ammonia from nitrates.

Ammonification refers to the formation of ammonium ions from nitrates.
When plants and animals die, or when animals emit wastes, the nitrogen in the organic matter re-enters the soil and water bodies where it is broken down by other microorganisms. This decomposition produces ammonia.
