Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).
Nitrogen fixation = fixing of atmosphere N2 to reactive form such as ammonia and nitrate . It can ether bt natural or synthetically.
1. Fixation bt living organism .
Exp . by Rhizobium , live in nodules of legume plant
2. Fixation by atmosphere
Exp , by lightning , huge energy involved cause N2 react with O2 form notrogen oxide and dissolve into soil
3. Fixation by haber process
to produce ammonia .
"Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen is relatively inert: it does not easily react with other chemicals to form new compounds. The fixation process frees nitrogen atoms from their triply bonded diatomic form, N≡N, to be used in other ways."
Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds (such as ammonia,nitrate and nitrogen dioxide). This is an essential process for life because fixed nitrogen is needed to make nucleotides which are needed to make DNA and also to make amino acids which in turn are needed to produce proteins. Nitrogen fixation is performed naturally by a number of different prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria. Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosises) with diazotrophs. Nitrogen fixation also occurs as a result of non-biological processes. These include lighting, industrially through the Haber-Bosch Process, and combustion.[2] Biological nitrogen fixation was discovered by the Dutch microbiologist Martinus Beijerinck.

It occurs mostly through bacteria.
The process of nitrogen-fixation is done by bacteria. Some live in the soil and roots of certain plants.
Nitrogen fixation which is the natural process of breaking down nitrogen from atmosphere to ammonia NH3. It is done either biologically or abiotically. This process is done by bacteria.

Effect of environmental stresses on nitrogen fixation, and explain prospects of making new symbiosis.
Nitrogen Fixation
the answer is "nitrogen fixation" because nitrogen fixation is The conversion of atmospheric nitrogen into compounds, such as ammonia, by natural agencies or various industrial processes.Read more: nitrogen-fixation
Nitrogen fixation is one process by which molecular nitrogen is reduced to form ammonia. This complex process is carried out by nitrogen-fixing bacteria present in the soil.
Nitrogen fixation is a biochemical process that transfer atmospheric nitrogen (N2) into NH3. The former is bio-unavailable, while the later one is bio-available. There is no analogy process for phosphorus.
The Nitrogen Cycle has five steps which include; Nitrogen Fixation, Nitrification, Assimilation, Ammonification, and Denitrification.
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.
Nitrogen fixation is carried out by nitrogen fixing bacteria in the nodules of the roots of legumes, and in the soil.
Nitrogen Fixation -Eugene Chung
Nitrogen fixation carried out by the microbes is known as biological nitrogen fixation.many microbes can fix nitrogen non-symbiotically like cyanobacteria,anabaena,etc whereas certain fix N2 symbiotically like rhizhobium species.
Conversion of inert elemental nitrogen gas into biologically usable form is called nitrogen fixation. Organism that performs nitrogen fixation is Rhizobium Leguminous.

Nitrogen Fixation
assimilation
Atmospheric Fixation:the enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth. Atmospheric nitrogen fixation probably contributes some 5– 8% of the total nitrogen fixed.
No. Nitrogen fixation is done by bacterias.
