Answer 2

The nitrogen cycle is the process by which the atmospheric nitrogen is fixed into several usable form.

Atmospheric nitrogen must be processed, or fixed, to be used by plants. Some fixation occurs in lightning strikes, but most fixation is done by free-living or symbiotic bacteria known as diazotrophs.

The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.

Thus, Due to constant presence of nitrogen cycle and thundering, concentration of nitrogen remains constant in the atmosphere.
