Nitrogen- fixing bacteria consume nitrogen in the air and change it into a for that plants can use.

Organic nitrogen can be found in living organisms, such as plants and animals, as well as in decaying organic matter in the soil. It is released through processes like decomposition and mineralization, contributing to the overall nitrogen cycle.
In plants, nitrogen is primarily absorbed in the form of nitrate (NO3-) and ammonium (NH4+). These forms are taken up by plant roots from the soil, where they are available due to the decomposition of organic matter and the activity of nitrogen-fixing bacteria. Nitrate is the most common form utilized by plants for synthesizing amino acids and proteins.
Bacteria that convert nitrite into nitrate are called nitrifying bacteria. These bacteria play a key role in the nitrogen cycle by facilitating the conversion of ammonia into nitrite and then into nitrate, which can be taken up by plants as a source of nitrogen for growth.
decomposers
Nitrate is both an organic & inorganic compound that can be created by decomposers (bacteria) and ester. Since plants grow out of soil, the soil layers contains nitrate bacterias that oxidizes ammonia as well as mix compounds of nitrogen and oxygen allowing plants to receive these materials from plant roots.
Plants cannot use organic nitrogen directly. "Microorganisms in the soil convert the nitrogen locked up in crop residues, human and animal wastes or compost to ammonium (NH4). A specific group of microorganisms convert ammonium to nitrate (NO3)" 58. Since nitrate is water-soluble, excess nitrate not used by plants can leach through the soil and into the groundwater.
Nitrogen gas is changed into a useful form for plants by nitrogen-fixing bacteria in the soil. These bacteria convert nitrogen gas into a form that plants can absorb and use to grow, known as ammonium or nitrate.
The three main roles are nitrate, nitrite, and denitrify. Nitrite is in the soil, and turns useful stuff into nitrate. Nitrate takes the useful stuff, is eaten by animals, and is decomposed. Denitrify is when once the animals release nitrate, it takes it back out and is released in the atmosphere.
They have mutualistic relationships with fungi and bacteria that can split atmospheric nitrogen into a form that is usable by the plants.
Nitrates are found in man-made fertilizers. They are also found in soil after the nitrogen fixating bacteria converts Nitrite to Nitrate (Nitrogen Cycle) which can be utilized by plants and consumed by the consumers.

The process of converting nitrate to nitrogen gas is called denitrification. This naturally occurs in soil, water, and sediment with the help of denitrifying bacteria. Denitrifying bacteria use nitrate as a source of oxygen and convert it into nitrogen gas, releasing it back into the atmosphere.
Bacteria use a process called nitrification to convert nitrogen to nitrate. First, ammonia (NH3) is oxidized to nitrite (NO2-) by ammonia-oxidizing bacteria. Then, another group of bacteria called nitrite-oxidizing bacteria convert nitrite to nitrate (NO3-).
