The air.
They are called nitryfying bacteria. Examples are Rhizobium, Anabena etc
Nitrogen-fixing bacteria
Chemoautotrophs like Nitrogen fixing bacteria
nitrites
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.

Chemoautotrophs like Nitrogen fixing bacteria
The bacteria that converts nitrogen gas into ammonia is known as nitrogen-fixing bacteria. Some examples of nitrogen-fixing bacteria include Rhizobium, Azotobacter, and Clostridium. These bacteria play a crucial role in the nitrogen cycle by making nitrogen available to plants.
nitrites
animals dont really need nitrogen but for plants, they need nitrogen and they get nitrogen usually in the form of nitrates or bacteria protein, by the work of nitrifying bacteria, putrefying bacteria and nitrogen fixing bacteria
Denitrofying bacteria help to metabolize nitrogen so that they can use the it. These bacteria take available nitrogen from the soil, as opposed to nitrifying bacteria that increase available nitrogen in the soil.

Nitrogen fixing bacteria, such as Rhizobium.
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
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.
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
