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.

By what process is nitrogen returned to the atmosphere by bacteria?
The process is called denitrification.
How is nitrogen returned to the air?
Nitrogen is released back into the atmosphere during the nitrogen cycle. This part of the cycle is called nitrogen fixation.
How does nitrogen get from organisms back into the atmosphere?
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.
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
nitrogen cycle
How much of earth's atmosphere is composed of nitrogen gas?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
How is nitrogen returned to the atmosphere in the nitrogen?
Denitrification by bacteria
By what process is nitrogen returned to the atmosphere by bacteria?
The process is called denitrification.
How is nitrogen part of the biosphere?
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.
What happens to nitrogen during decomposition?
It is returned to the atmosphere as a gas.
How is nitrogen returned to the air?
Nitrogen is released back into the atmosphere during the nitrogen cycle. This part of the cycle is called nitrogen fixation.
Which is common to the carbon nitrogen and water cycles?
The elements are returned back to the atmosphere. It is common in all the cycles.
How does nitrogen get from organisms back into the atmosphere?
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.
How does nitrogen returned to the atmosphere?
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.
How is Nitrogen used in the atmosphere?
Nitrogen is used in the atmosphere by.....
How does nitrogen get in the earths atmosphere?
Nitrogen gets into the earth's atmosphere through the nitrogen cycle.
Does the atmosphere have more nitrogen or oxygen in it?
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
What type of nitrogen is found in the atmosphere?
Nitrogen is found in the atmosphere as diatomic elemental nitrogen, N2.
