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.
Proteins are organic compounds, mostly composed of hydrogen, oxygen, nitrogen and carbon with some trace elements. The first three are obtained from water and the air, while the nitrogen and trace elements are acquired primarily via the roots from minerals (or fertilizer) in the soil.
Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
Soluble nitrogen refers to nitrogen compounds in soil that can dissolve in water, making them available for plant uptake. It includes forms such as ammonium (NH4+) and nitrate (NO3-). These forms of nitrogen are important for plant growth as they are readily accessible for use by plants.
Certain types of bacteria, such as Rhizobium and Azotobacter, can convert atmospheric nitrogen into a soluble form through a process called nitrogen fixation. These bacteria have the ability to convert atmospheric nitrogen gas (N2) into ammonium (NH4+), which can then be taken up by plants and used for growth.
these bacteria are known as rhizobium. they synthesis the atmospheric nitrogen into nitrates & nitrites soluble in soil
Nitrogen Fixation Bacteria are the primary source in which Nitrogen Fixation is carried out. The bacteria changes N2 (unreactive element) into nitrogen compounds, which are soluble and can be absorbed.

Nitrogen-fixating prokaryotes (such as bacteria) present in the roots of legumes and some other plants take N2 from the air and convert it to nitrogen compounds usable by plants. Nitrogen fixing bacteria (diazotrophs).

nitrogen cycle is important because the plants make protein from it. The rhizobeam present at the root noddles of legumes convert nitrogen into soluble form like nitrates and nitrides. this are absorbed by plants. animals eat the plants when they did their are certain bacteria present in the soil which convert the soluble form into atmospheric nitrogen. this is nitrogen cycle.

Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycleThey fix nitrogen into forms usable by plants.
because when bacteria convert ammonia into nitrates and nitrites, producers need them to make proteins, and then consumers eat the producers and reuse the nitrogen to make their own proteins.
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
