The Encyclopedia Britannica has a lot of great information on nitrogen fixing bacteria. According to the Encyclopedia Britannica nitrogen fixing bacteria are microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen.
Around 70-80% of nitrogen in the atmosphere is fixed by nitrogen fixing bacteria through a process called nitrogen fixation. This converted nitrogen is then made available for use by plants and other organisms in the environment.
Nitrogen-fixing bacteria
Most nitrogen is fixed by microorganisms in the soil, such as nitrogen-fixing bacteria like Rhizobium and Azotobacter. These bacteria convert atmospheric nitrogen into a form that plants can use, helping to make nitrogen available for plant growth.
Nitrogen can be fixed by lightning during thunderstorms, a process that converts nitrogen gas (N2) into nitrates (NO3-) that can be used by plants. Nitrogen can also be fixed by certain soil bacteria called nitrogen-fixing bacteria, which convert N2 into a form that can be taken up by plants.
No. Plants cannot use elemental nitrogen. The nitrogen must first be fixed, either by lightning or by nitrogen-fixing bacteria. Some plants have such bacteria in their roots.

carnivores -> herbivores -> plants -> nitrogen fixing bacteria
Chemoautotrophs like Nitrogen fixing bacteria
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.
Nitrogen can be fixed by lightning during thunderstorms, by industrial processes like the Haber-Bosch method, and through biological processes carried out by nitrogen-fixing bacteria in the soil.
The nitrogen-fixing bacteria live in the root nodules of legumes.
