​

Answer 1

Answer:

Rhizobium bacteria in soil convert free nitrogen to soluble nitrates. This is nitrogen fixation.

Answer 2

Nitrogen fixation

Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia (NH. 3) or related nitrogenous compounds in soil. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms.
