By various processes such as nitrogen fixation, nitrification, and ammonification.
Nitrogen fixation
the answer is nitrogen fixation
Some essential nitrogen compounds can be absorbed by plants from the soil in which they grow. the nitrogen compounds can be provided to the soil by nitrogen-fixing bacteria living in association with the plants and/or from fertilizers. Some nitrogen compounds can also be input to the soil from lightning strikes that provide activation energy to facilitate the reaction of atmospheric nitrogen to produce absorbable nitrogen compounds that can be carried into soil by rain.
Yes. Vascular plants can absorb nitrogen compounds such as nitrates from the soil on their own.What plants can't do on their own is fix nitrogen from the air into nitrogen compounds. Some plants including legumes (such as peas, beans, lupins) and casuarinas form symbioses with nitrogen-fixing bacteria to form nitrogen into nitrogen compounds.
From lightening and nitrogen-fixing bacteria in the roots of certain plants.

Nitrogen fixation
the answer is nitrogen fixation
Nitrogen compounds known as Nitrates found in the soil
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Many species of soil bacteria fix nitrogen,that is, they convert it into compounds that are readily absorbed by plants.

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

By the process denitrification. Some bacteria do that also human
