It allows nitrogen atoms to continually cycle through the biosphere.
Cyanobacteria can affix atmospheric nitrogen (N2).

Nitrogen fixing bacteria are anaerobic bacteria present in the soil or in some plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds (e.g. ammonium salts) that plants can use in the soil.Nitrogen fixing bacteria that are symbiotic with plants use sugars supplied by the plant they live in to provide the metabolic energy to carry out this process.
Certain types of soil bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a usable form for plants. This process helps to replenish soil with nitrogen, which is an essential nutrient for plant growth. Leguminous plants also have symbiotic relationships with nitrogen-fixing bacteria in their root nodules, allowing them to utilize atmospheric nitrogen.
nodules
Certain bacteria and archaea have the ability to transform unusable nitrogen gas (N2) from the atmosphere into a form that plants can use, a process known as nitrogen fixation. Some examples include symbiotic nitrogen-fixing bacteria like Rhizobium that form nodules on plant roots, as well as free-living nitrogen-fixing bacteria like Azotobacter and cyanobacteria.
Nitrogen fixation occurs in leguminous plant that have nitrogen fixing bacteria in the root nodule. The plants utilize the nitrogen from the nitrogen fixing bacteria. The bacteria utilize plant sugars formed via photosynthesis.
Root nodules are the specialized structures in plants that serve as a home for nitrogen-fixing bacteria, such as Rhizobium species. These bacteria are able to convert atmospheric nitrogen into a form that the plant can use for growth, providing an important source of nitrogen for plant nutrition.
many types of pea crop.. The roots of these plants house nitrogen fixing bacteria :) i think a type of potato plant does has them as well Pea, gram and ground nut (pea nut)
Legume plants have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia. These bacteria convert atmospheric nitrogen into a form that the plants can use for growth, which benefits both the plant and the bacteria. Examples of legume plants include peas, beans, and clover.
