How do nitrates produced?
in nature nitrogen from the atmosphere is converted to ammonia by nitrifying bacteria ammonia is then converted to nitrite and then to nitrate by nitrogen fixing bacteria. nitrate is converted back to nitrogen by denitrifying bacteria
How do humans add nitrogen to the atmosphere?
by breathing co2 back into the air. Therfore magically making it nitrogen.
How is the element nitrogen N in nitrogen compounds in soil released back to the air?
denitrifying bacteria For a fuller exposition see wikipedia for 'nitrogen cycle'.
Outline the major steps in the nitrogen cycle?
The major steps in the nitrogen cycle: nitrogen moves from the air to the soil, into living things, and back into the air
Is liquifying nitrogen a chemical change?
It is a chemical change because it can change back if you refreeze the nitrogen and it changed the chemical.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
nitrogen cycle
What is denitrification?
Denitrification is the process of releasing nitrogen back into the atmosphere. It may also be nitrates transforming into nitrogen.
Nitrates are turned back into nitrogen gas by?
Soil bacteria!!!!
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).
What occurs when anaerobic bacteria break down nitrates and release nitrogen gas back into the atmosphere?
denitrification
What are the three types of bacteria involved in nitrogen cycle?
The three types of bacteria which are involved in the nitrogen cycle are nitrogen- fixing bacteria which change the nitrogen gas into ammonia. The next is nitrifying bacteria which changes the ammonia into nitrities and then the nitriites into nitrates. Then the plant absorbs the nitrates and uses them to continue growth. Then an animal may eat the plant receiving the nitrogen from it. But it must eventually get ride of it so it produces waste which goes back into the soil and is broken down by decomposers and fungi, which then turn it back into ammonia. The cycle then repeats itself. Extra nitrates are turned back into nitrogen gas by denitrifying bacteria.
Why are nitrogen fixing bacteria important?
Although the air is made up of about 80% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle
What is the transfer of nitrogen from air to soil to organism and back to air and soil?
nitrogen cycle
What is the transfer of nitrogen from air to soil to organism and back to air or soil?
nitrogen cycle.
How does dead organism return inorganic nitrogen back to earth?
How do dead organism return inorganic back to the earth
How do nitrates produced?
in nature nitrogen from the atmosphere is converted to ammonia by nitrifying bacteria ammonia is then converted to nitrite and then to nitrate by nitrogen fixing bacteria. nitrate is converted back to nitrogen by denitrifying bacteria
What role do bacteria play the nitrogen cycle?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycleThey fix nitrogen into forms usable by plants.
