The atmosphere is the reservoir for nitrogen in the nitrogen cycle, where it makes up about 78% of the air we breathe. Nitrogen gas can be converted into forms that are usable by plants and animals through processes such as nitrogen fixation, nitrification, and denitrification. While nitrogen can be found in other locations such as soil and biomass, these are not considered to be the primary reservoir for nitrogen in the nitrogen cycle.
