Nitrates can be changed back into nitrogen through a process called denitrification. This process is carried out by denitrifying bacteria in the soil, which convert nitrates into nitrogen gas under anaerobic conditions. This nitrogen gas is then released back into the atmosphere.

What organism turns nitrates back into nitrogen gas?
Denitrifying bacteria are responsible for converting nitrates back into nitrogen gas as part of the nitrogen cycle. These bacteria thrive in oxygen-poor environments and break down nitrates into nitrites and eventually into nitrogen gas.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances b?
Nitrogen is changed into ammonia by nitrogen-fixing bacteria in soil and water. This ammonia can then be further converted into nitrites and nitrates by other species of bacteria in a process called nitrification. These nitrates are then used by plants to make proteins and other essential molecules.
Although air is full of nitrogen it is not available for organisms to readily use. Nitrogen is changed into which substances before being used by living things?
Nitrogen is changed into ammonia and nitrates through the process of nitrogen fixation before being used by living things. This conversion is typically carried out by specialized bacteria in the soil or water.
Outline the major steps in the nitrogen cycle?
Nitrogen fixation: Bacteria convert atmospheric nitrogen into ammonia. Nitrification: Ammonia is converted into nitrites and then nitrates by nitrifying bacteria. Assimilation: Plants and other organisms take up nitrates to build proteins and nucleic acids. Ammonification: Decomposers break down organic matter releasing ammonia back into the soil. Denitrification: Denitrifying bacteria convert nitrates back into atmospheric nitrogen, completing the cycle.
What are the four stages of the nitrogen cycle?
The four stages of the nitrogen cycle are nitrogen fixation, nitrification, assimilation, and denitrification. During nitrogen fixation, nitrogen gas is converted into ammonia by bacteria. Nitrification involves the conversion of ammonia into nitrites and nitrates. Assimilation is the process of incorporating nitrogen into living organisms. Denitrification converts nitrates back into nitrogen gas.
What organism turns nitrates back into nitrogen gas?
Denitrifying bacteria are responsible for converting nitrates back into nitrogen gas as part of the nitrogen cycle. These bacteria thrive in oxygen-poor environments and break down nitrates into nitrites and eventually into nitrogen gas.
Which bacteria can release nitrogen from nitrates and nitrites in the soil back to the atmosphere?
The bacteria that can release nitrogen from nitrates and nitrites in the soil back to the atmosphere are called denitrifying bacteria.
What occurs when anaerobic bacteria break down nitrates and release nitrogen gas back into the atmosphere?
When anaerobic bacteria break down nitrates, they can denitrify the nitrates and release nitrogen gas (N2) back into the atmosphere. This process is called denitrification and it helps return nitrogen to the atmosphere in its inert form.
What is the formation of oxides of nitrogen and eventually nitrates as nitrogen fixing?
Reactions for the formation of oxides of nitrogen and nitrates as nitrogen fixing

Nitrogen cycle in order?
The nitrogen cycle begins with nitrogen fixation, where nitrogen gas is converted into ammonia by bacteria. Ammonia is then converted into nitrites and nitrates by nitrifying bacteria. Plants take up nitrates as nutrients, which are then consumed by animals. Finally, denitrifying bacteria break down nitrates back into nitrogen gas, completing the cycle.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
called denitrification. This process releases nitrogen gas back into the atmosphere, completing the nitrogen cycle. Denitrification occurs under anaerobic conditions where bacteria use nitrates as an alternative electron acceptor in the absence of oxygen.
What form of nitrogen is returned to the atmosphere by plant?
Your answer is invalid, because the plants return the nitrogen back in to the air. I think what you're trying to ask is what forms of nitrogen is taken by the plants. The answer is nitrides, and nitrates. Nitrides are formed by decomposers in the soil and further nitrogen fixation causes nitrides into nitrates. You can notice this through their equation: nitrides (n3) nitrates (no3).
The conversion of nitrates to nitrogen gas by bacteria is called?
Nitrogen Fixation.
Which bacteria decompose nitrates in the soil into free nitrogen?
Denitrifying bacteria, such as Pseudomonas and Paracoccus species, carry out the process of denitrification, converting nitrates in the soil into free nitrogen gas. This process helps to return nitrogen gas back to the atmosphere, completing the nitrogen cycle.
What is a plant's role in the nitrogen cycle?
Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
