Answer 1

Answer:

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.

Answer 2

Answer:

Nitrogen at about 78% of the air provides, at least, an inert gas with respect to breathing with which to mix with oxygen. Living things have evolved breathing a 20.8% oxygen atmosphere and if the oxygen was higher it would become a problem.
