Nitrogen gas is more abundant in our atmosphere than oxygen! However, nitrogen needs to be converted into different forms to be used by many organisms. Bacteria are highly involved in this. Describe the role of A bacteria fixing nitrogen and they live symbiotically with some plant species, B nitrifying bacteria, and C denitrifying bacteria in the nitrogen cycle.

A) The role of bacteria fixing nitrogen is very important because it fixes atmospheric nitrogen in the roots of plants. For example, Azotobacter is a bacteria which lives in the root of the higher plants. The bacteria fixes nitrogen for the plant and the plant gives habitat and food to the bacteria and hence, both get benefit.

Bacteria fixing nitrogen is vital for fixing the atmospheric nitrogen that can be found in the roots of plants.

Nitrogen is a component of nucleic acid and proteins and this is essential to life on Earth. Bacteria fixing nitrogen transforms nitrogen gas that's gotten from the atmosphere into the fixed nitrogen like ammonia that can be used by the plants.

Nitrifying bacteria are microorganisms that are vital in the nitrogen cycle as they convert soil ammonia to nitrates which are used by plants.

Denitrifying bacterias are the bacteria that convert nitrates into nitrogen-containing gases. This is vital for the completion of the nitrogen cycle as nitrogen is recycled into the atmosphere.
