Question

How is the amount of nitrogen remains fixed in the air even after being used up by the plants?​

Answer 1

Explanation:

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

Answer 2

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.
