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
What is denitrification?
Denitrification is the process of releasing nitrogen back into the atmosphere. It may also be nitrates transforming into nitrogen.
What process releases nitrogen gas into the atmosphere?
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-MD
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.
What is an explanation of the nitrogen cycle?
Nitrogen cycle begins like every other cycle in the Biogeochemical cycle.Nitrogen is an unstable gas in it's octet form but the normal Nitrogen is stable so during nitrogenation;which is the formation of free Nitrogen in the atmosphere,nitrogen is being broken down during lightening and thunderstorms so,it becomes free in the atmosphere and can now combine with other compounds.During rainfall,Nitrogen combines with water to form Nitric acids and with sulphur to form NITROGEN SULPHIDE.These two compounds of Nitrogen are then incorporated into the soil during Nitrogen fixation. The soil alone can not convert this Nitrogen into usable or rather consumable Nitrogen so only root noddles of leguminous plants like Beans can convert this nitrogen into usable one because they have nitrogen fixing bacteria like Rhizobium nigricans . But there are also some free living bacteria in the soil named Azotobacter which help in converting this nitrogen in the soil into usable Nitrogen so that plants can use it for growth.When these nitrogen compounds have been converted into usable nitrogen,plants now use it to produce food energy which are later on eaten upon by animals for growth.This process is called feeding like we all know.When these plants and animals die,their dead bodies decay and are embedded into the soil.Micro organisms now eat on these dead bodies.A process called putrefaction.These decomposed matters are later on converted into Ammonia in a process called Amonification by nitrogen fixing bacteria.The same Ammonia is converted into Nitrites and later on into nitrates by Nitrosomonas and Nitrobacters bacteria respectively and some of the nitrates are lost into the underneath soil a process called leaching during erosion by water and the nitrates are also absorbed by plants during food chain a process called Assimilation.The nitrates and nitrites are later sent back into the atmosphere during denitrification which 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 as Pseudomonas 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.Without forgetting that during thunder storms,Nitrogen is also sent back into the atmosphere.
What kind of organisms can remove nitrogen from the atmosphere?
Bacteria can remove nitrogen from the atmosphere.
What is organisms that can be transform unusable nitrogen in the atmosphere into chemical compounds containing nitrogen that can be used by other organisms?
Nitrogen-fixing bacteria
What is the cycle involving the exchange of nitrogen between organisms and the atmosphere?
nitrogen cycle
What are the most organisms unable to take from the atmosphere?
Nitrogen.
What kind organisms can remove nitrogen from the atmosphere?
connor
What is responsible for making nitrogen in the atmosphere usable by living organisms?
nitrogen fixing bacteria
Which organisms act as a bridge between the nitrogen in the atmosphere and the organisms of the biosphere?
bacteria
What is the difference between nitrogen and carbon cycles?
The cycling of carbon between the atmosphere, land, water, and organisms. But the nitrogen is between the environment and organisms.
What is the transfer of nitrogen from the atmosphere to plants and back to the atmosphere or directly into plants again?
Nitrogen cycle
What elements are most organisms unable to take from the atmosphere?
nitrogen
What is the need of nitrogen in atmosphere?
What does it mean to say the "need of nitrogen in the atmosphere"? Needed for who, for what? Nitrogen is in the atmosphere regardless of who needs it.Is the nitrogen gas used for something? Definitely. Certain organisms are able to convert nitrogen gas, N2, in the atmosphere into NH3, ammonia, which is used as a plant nutrient. This is generally called nitrogen fixation.
Give two examples of how nitrogen cycles from the abiotic portion of the environment into living things and back?
when an animal urinates nitrogen returns to the water or soil,and when organisms die and decay,nitrogen returns to the soil and eventually to the atmosphere
