Bacteria Certain bacteria can use nitrogen from the air to make nitrogen-containing substances called nitrites. Other bacteria can turn nitrites into nitrates-another group of nitrogen-containing substances.
nitrogen can be three different substances as a solid, liquid, and a gas.

Itβs an element
Air and soil.
The substances represented by the chemical formula N2 is nitrogen gas.
Three substances are water, nitrogen, and access salts.
Nitrogen fixation is the conversion of atmospheric nitrogen, N2, into some biological form, such as ammonia, NH3, or nitrogen dioxide, NO2. In nature, this process is most often completed by nitrogen-fixing bacteria or diazotrophs. Nitrogen fixation is important because only fixed nitrogen can be used for basic biological substances such as proteins and nucleic acids.
Oxygen, Nitrogen, Estrogen
Proteins are a class of such substances.
