Best Answer - Chosen by VotersThe only abiotic element in the nitrogen cycle I know of is lightning. Lightning bind nitrogen and some other stuff to form nitrates. There are certain bacteria, primarily found on the roots of legumes, that also partake in nitrogen fixation. Then there are all the other organisms that utilize this nitrogen and eventually release it back into the cycle.
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.
The process of combining free nitrogen with other elements is called nitrogen fixation. This can occur through biological processes such as symbiotic relationships with certain plants and bacteria, or through non-biological processes such as lightning and industrial methods like the Haber-Bosch process. In these processes, atmospheric nitrogen is converted into forms that can be utilized by living organisms, such as ammonia or nitrate.
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.
Denitrification is caused by specialized bacteria, such as Pseudomonas and Paracoccus, that can convert nitrate (NO3-) into nitrogen gas (N2) or nitrous oxide (N2O) under anaerobic conditions. These bacteria play a crucial role in the nitrogen cycle by returning nitrogen to the atmosphere.

The process of bacteria turning usable nitrogen into nitrogen gas is called denitrification. This occurs when certain bacteria convert nitrates or nitrites back into nitrogen gas, which is released into the atmosphere. This can result in a loss of available nitrogen for plants and other organisms.
diazotrophs.
ok so............... nitrogen fixation helps the plants and the bacteria to convert atmospheric nitrogen into the amonia ....amonium...nitrate and nitrite {simple substances of nitrogen}............these are the only forms of nitrogen that could be used by the plants
Bacteria in soil obtain their nitrogen primarily from organic matter, such as dead plants and animals. They can also obtain nitrogen through nitrogen fixation, a process where certain bacteria convert atmospheric nitrogen into a form that plants can use.
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 Bacteria are the primary source in which Nitrogen Fixation is carried out. The bacteria changes N2 (unreactive element) into nitrogen compounds, which are soluble and can be absorbed.
In soil. Especially around certain plants (legumes).
Bacteria
The process you have mentioned is called nitrogen fixation. It is done by bacteria named Rhizobium Bacillus.
