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 is nitrogen returned to the atmosphere?
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.
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
What is it called when bacteria convert nitrogen into ammonia?
The process you have mentioned is called nitrogen fixation. It is done by bacteria named Rhizobium Bacillus.
How do plants get nitrogen from the atmosphere?
Direct nitrogen fixation is performed by a rather specific kind of organism that probably lived free before the atmosphere began to contain oxygen. Today these are anaerobic bacteria that live in nodules on the roots of plants, particularly the legumes. The actual process is brought about by enzymes called nitrogenases. It is an energy intensive process, requiring a lot of ATP in acid conditions. To fix one molecule of nitrogen requires sixteen ATP molecules and the product is ammonia, which is immediately converted to ammonium ion by acid hydrogen. This is still not available to the plant, but if excreted into the soil other aerobic bacteria convert it to nitrite using oxygen, and then nitrate, and this is available to the plant. Another pathway is to convert the ammonium directly into glutamic acid, which the plant can use directly to generate protein.

What would happen if the bacteria that cause denitrification were removed from the nitrogen cycle?
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.
What process is nitrogen returned to the atmosphere by bacteria?
The process is called denitrification.
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
What releases nitrogen into the atmosphere?
Denitrification which is the process of nitrofen returning to the atmosphere which also involes denitrifying bacteria( convert nitrate back into nitrogen gas)
What is the role of microorganisms in returning nitrogen or carbon dioxide to the atmosphere?
this microorganisms is called denitrifying bacteria, it helps to decompose the nutrients (nitrogen) back to the atmosphere. and the process of returning nitrogen or carbon dioxide to the atmosphere is called denitrification.

What process involves the capture and conversion of nitrogen into a form usable by plants?
Nitrifying bacteria can convert atmospheric nitrogen in to nitrates that plants can use in the soil. That is why leguminous plants having these micro-organisms in the nodules enrich the soil for nitrogen deficiency.
What do nitrogen fixing bacteria convert in the nitrogen cycle?
Nitrogen fixing bacteria are anaerobic bacteria present in the soil or in some plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds (e.g. ammonium salts) that plants can use in the soil.Nitrogen fixing bacteria that are symbiotic with plants use sugars supplied by the plant they live in to provide the metabolic energy to carry out this process.
How is nitrogen from the atmosphere brought into the ground?
Nitrogen in the atmosphere is converted into nitrogen in the soil by a process called nitrogen fixation, which is carried out by a number of different types of bacteria. Some of these bacteria grow on the roots of certain plants, such as clover, alfalfa, and peanuts, and provide nitrogen to the plant and the soil. ----------------------------------------- Lightning also causes some atmospheric nitrogen to be converted into oxides of nitrogen. These dissolve in rain water and are brought to the ground in the rain.
What is a nitrogen-fixing?
nitrogen fixing is a process in which atmosphere nitrogen converted into ammonia.
