Some of it is fixed by legume plants - or more precisely by bacteria in plant nodules.
Some gets there by when compounds created by lighting dissolve into the accompanying rain.

How do plants and animals get nitrogen if not from the atmosphere?
if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
Where does nitrogen in the soil come from?
Nitrogen compounds known as Nitrates found in the soil
Where does most of the nitrogen that the bacteria use come from?
The nitrogen is absorbed into the soil from the atmosphere.
Which parts of the nitrogen cycle are involved in moving nitrogen from the atmosphere into the soil?
2 and 4
What is the role of nitrogen fixing bacteria?
they help balance the level of nitrogen in the soil and atmosphere.

How do you separate nitrogen from soil?
Bacteria in the soil called nitrogen-fixing bacteria go through a process called nitrogen-fixation which allows nitrogen to enter the atmosphere

How is Nitrogen stored in the biosphere?
The largest store of nitrogen is atmosphere, where it exists as nitrogen gas. Other major stores of nitrogen includes oceans and organic matter in soil.
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
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.
What converts nitrogen in the nitrogen cycle?
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
How is nitrogen cycle?
when nitrogen go from soil to back in atmosphere due to nitrogen fixing bacteria then it again return to soil due to lightning, dead animals, roots of plants and by other ways. and again go to atmosphere in this way nitrogen cycled.
