Nitrogen (N2) is always in the atmosphere however if you are talking about how it gets released into the atmosphere after it is fixated by lightning absorbed by plants and eaten by 1st level consumers when they or the plant itself decomposes nitrogen it is released back into atmosphere.
That's the short of it. Go to wikipedia or read a ecology journal if you wan't to know all the chemicals, reactions, etc in the process

"It leave the atmosphere through evaporation," says this person. However, evaporation is a concept that applies to the water cylce. Nitrogen can enter the atmosphere by several ways, inculding volcanic eruptions and denitrification.
Nitrogen-fixation helps nitrogen leave the atmosphere.

Denitrification which is the process of nitrofen returning to the atmosphere which also involes denitrifying bacteria( convert nitrate back into nitrogen gas)
denitrification-it changes nitrates back into nitrogen gas
Nitrogen is released into the atmosphere via many ways.
-Fossil Fuels, at industries
-The use of vehicles
-Power Plants
-Sewage
-Human Activities
denitrifying bacteria
atmosphere as N2 gas
Nitrogen return to the atmosphere by the process of Denitrification. Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such asPseudomonas and Clostridium in anaerobic conditions. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.
denitrification
denitrification is soil bacteria converting nitrates into nitrogen gas, is process releases nitrogen into the atmosphere. If there wasn't any bacteria, there would be no process and therefor the nitrogen wouldn't make it into the atmosphere.

Atmosphere causes 78% nitrogen to be released as a gas
When organisms die, decomposers return nitrogen to the soil as ammonia. The ammonia may be taken up again by producers. Other soil bacteria convert nitrates into nitrogen gas in a process called denitrifrication. this process releases nitrogen into the atmosphere once again.
Nitrogen gas in the soil is used by plants, which are eaten by animals. The waste products of the animals contain the nitrogen. It is broken down by bacteria, which releases nitrogen gas into the atmosphere, and the cycle repeats.
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
The most abundant gas in the Earth's atmosphere is nitrogen.
The nitrogen gas present in the atmosphere is called atmospheric nitrogen. About 78% of the Earth's atmosphere is made of nitrogen gas.
The answer choices are:Plants take in nitrogen gas from the atmosphere.Bacteria convert nitrogen gas into a form that plants can use.Water absorbs nitrogen.Animals take in nitrogen gas from the atmosphere.
Nitrogen is the first abundant gas in our atmosphere.
the most abundant gas of the atmosphere is nitrogen with high percentage 78.09
nitrogen is the most abundant gas about 70 percent is nitrogen in atmosphere
