Which best describes nitrogen fixiation
A. Nitrogen fixiation is the process of creating free nitrogen for plants to absorb.
B. Nitrogen fixiation is the breakdown of nitrogen in the soil.
C. Nitrogen fixiation is the conversation of nitrogen gas into a usable form.
D. Nitrogen fixiation is the destruction of the bonds between nitrogen and other elements.

Explanation:

Nitrogen fixation is a process by which molecular nitrogen in the air is converted into ammonia 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.
