Which process returns nitrogen to the atmosphere, completing the nitrogen cycle?

Denitrification (correct)

Nitrogen fixation

Assimilation

Nitrification

What is the importance of ammonification in the nitrogen cycle?

It converts ammonia into nitrite and then into nitrate, which plants can readily take up from the soil.

It incorporates nitrogen into biological tissues, essential for the growth and development of living organisms.

It provides plants with a form of nitrogen they can absorb and use for growth.

It returns nitrogen to the soil, making it available for reuse. (correct)
