True
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-fixating prokaryotes (such as bacteria) present in the roots of legumes and some other plants take N2 from the air and convert it to nitrogen compounds usable by plants. Nitrogen fixing bacteria (diazotrophs).
I don't think the ocean produces nitrogen or oxygen for that matter. Nitrogen comes from fusion (in a star, hydrogen turns into helium, which in turn changes into heavier elements). The ocean may store some nitrogen as a dissolved gas and nitrogen in the form of compounds such as NH3 and other soluble salts.
Lightning changes the nitrogen in the air into another form called nitrate.THE NITRATE IS BROUGHT DOWN TO THE SOIL BY RAIN.Nitrate is the only form of nitrogen that can be absorbed by plants through its roots.--hhahahah
Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.

Plants use nitrogen a N- and air has N2. Nitrogen fixation changes nitrogen into a form that plants can use.

Nitrogen gas is converted into a form that plant cells can use through a process called nitrogen fixation. This can be done by certain bacteria that live in the soil or in the root nodules of leguminous plants. These bacteria convert nitrogen gas into ammonia, which can then be taken up by plant roots and used to synthesize proteins and other essential molecules.
The nitrogen cycle involves both physical and chemical changes. Physical changes include nitrogen fixation by bacteria and nitrification, while chemical changes include denitrification and ammonification.
Changes in the nitrogen cycle can be caused by human activities such as the use of synthetic fertilizers, which increase nitrogen levels in soils and water systems, leading to eutrophication. Deforestation and land-use changes can disrupt natural nitrogen fixation processes, while industrial emissions contribute to nitrogen oxides in the atmosphere, affecting air quality and climate. Additionally, agricultural practices, such as livestock farming, release ammonia and disrupt the balance of nitrogen compounds in ecosystems. Climate change can also alter nitrogen cycling through changes in temperature and precipitation patterns.

Nitrogen gas is converted into nitrates through a process called nitrogen fixation, which is carried out by certain bacteria in the soil or by lightning strikes. These bacteria take atmospheric nitrogen and convert it into a form that plants can use to grow, known as nitrates.

Nitrogen can form a variety of compounds with oxygen, in which nitrogen has different valences, because reactions do not always go to completion, and oxidation does not always go to a state of maximum oxidation; the concentration of the reactants, the temperature at which the reaction takes place, and other variables affect the result.
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
