Through nitrogen fixation. It becomes this through cyanobacteria or nitrogen fixing bacteria. Helpful critters!
Atmospheric Fixation: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. Atmospheric nitrogen fixation probably contributes some 5– 8% of the total nitrogen fixed.
Yes, in fact, nitrogen is the most abundant gas. The atmospheric gas we call air is made up of 78% nitrogen.
Oxygen and Nitrogen
I believe the 3 most dominant gases of our atmosphere are nitrogen, carbon dioxide and methane
Nitrogen, making up 75% of the Earth's atmosphere.
The most common atmospheric gas is nitrogen, which makes up about 78% of the Earth's atmosphere.
The nitrogen gas present in the atmosphere is called atmospheric nitrogen. About 78% of the Earth's atmosphere is made of nitrogen gas.

Oxygen and Nitrogen
78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide
Oxygen (~21%) is second to nitrogen (~78%) in the composition of Earth's atmosphere.
The atmosphere of Earth features oxygen and nitrogen. Small quantities of other gasses such as Argon can also be found throughout the air.

Any freshwater on Earth is usable
Nitrogen, making up 75% of the Earth's atmosphere.
Nitrogen Fixation is a process of combining atmospheric nitrogen with other elements to form useful compounds. Nitrogen is essential to living things, but most organisms cannot use nitrogen that is not combined with other elements. This is why nitrogen fixation is important to the continuation of life on earth.
