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.

The process is called denitrification.
Nitrogen is released back into the atmosphere during the nitrogen cycle. This part of the cycle is called nitrogen fixation.
Nitrogen used by plants and animals is returned to the atmosphere by the action of bacteria. Bacteria break down proteins to obtain energy, releasing nitrogen back into the air in the process.

The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Denitrification by bacteria
The process is called denitrification.
It's continuously processed in the nitrogen cycle. In broad outline nitrogen in the atmosphere is fixed by bacteria so that it's available to plants making protein. This protein is consumed by animals and plants or returned to the atmosphere as methane. The plant nitrogen is converted to animal protein which is eventually returned to the atmosphere by bacteria. For more detail you might wish to refer to information on wikipedia.
It is returned to the atmosphere as a gas.
Nitrogen is released back into the atmosphere during the nitrogen cycle. This part of the cycle is called nitrogen fixation.
The elements are returned back to the atmosphere. It is common in all the cycles.
Nitrogen used by plants and animals is returned to the atmosphere by the action of bacteria. Bacteria break down proteins to obtain energy, releasing nitrogen back into the air in the process.
When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use. Other types of bacteria are able to change nitrogen dissolved in waterways into a form that allows it to return to the atmosphere.
Nitrogen is used in the atmosphere by.....
Nitrogen gets into the earth's atmosphere through the nitrogen cycle.
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
Nitrogen is found in the atmosphere as diatomic elemental nitrogen, N2.
