Question

The process of nitrogen fixation converts: [1]

A
molecular nitrogen to atomic nitrogen

B
molecular nitrogen to nitrate and ammonia

C
ammonia to molecular nitrogen

D
atomic nitrogen to nitrate and ammonia

E
nitrate to molecular nitrogen

Answer 1

D

atomic nitrogen to nitrate and ammonia

Explanation:

Nitrogen fixation is the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. In nature, most nitrogen is harvested from the atmosphere by microorganisms to form ammonia, nitrites, and nitrates that can be used by plants.
