They live in the root nodules of leguminous [pea] Plants, and they perform the crucial function of taking inorganic N2 [from Our Atmosphere] and transforming that into biologically useful NO2!

Some types of archaea and some species of cyanobacteria are also capable of performing nitrogen fixation. In addition, certain plants, such as legumes, have symbiotic relationships with nitrogen-fixing bacteria in their roots, allowing them to obtain fixed nitrogen in exchange for providing sugars to the bacteria.
Bacteria are the only organisms that can convert nitrogen into a usable form. Diazotroph or nitrogen-fixing bacteria are types of bacteria that perform this ability.
Bacteria return nitrogen to the soil through a process called nitrogen fixation, where they convert atmospheric nitrogen into a form that plants can use. This allows plants to obtain the necessary nitrogen for their growth and, in turn, enriches the soil with nutrients.
Despite their relative simplicity, bacteria carry out most of the key chemical changes of carbon, nitrogen, and sulfur in the living world. The eukaryotes, like us humans, perform relatively small changes to their molecules. Benefits of bacteria include: * Bacteria are the only living things which can fix nitrogen. They are therefore essential to all other life on Earth. * Some plants such as beans keep nitrogen fixing bacteria as symbionts in nodules on their root. * Bacteria are the major decomposers of dead plants and animals, so freeing their atoms to be re-used by other living things. * Cows and other animals keep bacteria in their stomachs, as only bacteria can break down the tough cell walls of plants. * People use bacteria to turn wine into vinegar and milk into cheese and yogurt. * They are increasingly used in biotechnology to manufacture proteins.
In the nitrogen cycle, nitrogen-fixing bacteria play a crucial role in converting gaseous nitrogen (N₂) into ammonia (NH₃). These bacteria, such as Rhizobium, live in the root nodules of legumes or in the soil, where they convert atmospheric nitrogen into a form that plants can use. Additionally, some free-living bacteria, like Azotobacter, also perform this nitrogen fixation in the soil. This process is essential for replenishing the nitrogen available to plants and, consequently, the entire ecosystem.
Nitrogen needs to be fixed before it is used by plants.

Bacteria in soil play important roles in nutrient cycling, decomposition of organic matter, and enhancing soil structure. They can also help plants by fixing nitrogen, promoting root growth, and suppressing harmful pathogens. Overall, bacteria contribute to the overall health and fertility of soil ecosystems.

Bacteria and plant roots perform nitrogen fixation, which allows plants to use the nitrogen. Nitrogen is used in cells to build proteins and DNA. However, plants get their nitrogen as "nutrients" in the soil.
Bacteria return nitrogen to the soil through a process called nitrogen fixation, where they convert atmospheric nitrogen into a form that plants can use. This allows plants to obtain the necessary nitrogen for their growth and, in turn, enriches the soil with nutrients.
Some bacteria have the ability to "fix" nitrogen, that is they can utilize gaseous (atmospheric) nitrogen to produce organic compounds. (They can all break down compounds to free nitrogen too.)
Bacteria with the ability to perform nitrogen fixation, such as Rhizobium and Azotobacter, have an enzyme called nitrogenase that enables them to convert atmospheric nitrogen gas (N2) into ammonia (NH3). This process is essential for making nitrogen available to plants for growth and survival.
