The conversion of nitrates (NO2) into nitrogen gas (N2) which is then released into the atmosphere.
A chemical reaction that breaks down compounds into simpler products.
Microscopic living organisms, usually one-celled, that can be beneficial or dangerous.
Nitrogen gas (N2)

A chemical that includes nitrogen and oxygen, often used as a fertilizer. They are inorganic compounds that can be found in nature and in several foods we eat.
The cycling of nitrogen between organisms, soil, water, and the atmosphere
converts nitrogen gas from the air into nitrates
Cannot be used by organisms unless it goes through the nitrifying process by bacteria.
