$\sf \large \purple{importance - }$

1. Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems.
2. 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.
