Question

2.what do you mean by nitrogen fixation
​

Answer 1

Answer:

the chemical processes by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle.

Answer 2

Answer:

Nitrogen fixation is the capture of literally unlimited atmospheric nitrogen gas (N2) to form ammonia (NH3), which is readily available for assimilation by plant and microbes.

Explanation:

Nitrogen fixation is the bacterial process whereby molecular N2 gas is converted to reactive, biologically available forms of nitrogen.

Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems. A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and nitrogen dioxide, NO2.
