nitrogen cycle
The conversion of ammonia to nitrate (nitrification) is performed primarily by soil-living bacteria and other nitrifying bacteria. It is important for the ammonia to be converted to nitrates because accumulated nitrites are toxic to plant life. Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle.
Soil bacteria!!!!
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.
denitrification
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 cycle. Some nitrifying bacteria lives in the roots of legumes, and do the same job.

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

denitrification
nitrification= it is the conversion of ammonia first into nitrites then into nitrates by nitrifying bacteria. dentrification=it is the conversion of nitrites and nitrates into free nitrogen.
Legumes have nitrifying bacteria in their roots, but mostly it is found in the soil. Although the air is made up of about 78% 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
