Question

Ammonification (production of ammonia) takes place during the process of

• A. Respiration.
• B. Photosynthesis.
• C. Fermentation.
• D. Nitrogen fixation.
• E. None of the above.

Answer 1

The correct option is D Nitrogen fixation.

In ammonification, the bacteria break down organic matter into ammonia (nitrogen fixation). This can be converted into nitrites and nitrates and used by plants as nutrients (nitrification). The organic matter can include dead and decomposed animal bodies or their excreta. It is a step of the nitrogen cycle.

So, the correct answer is option D.
