Nitrogen-fixing bacteria
Nitrogen fixing bacteria, such as Rhizobium.
Nitrogen fixation is a uniquely prokaryotic. This a one celled organism.
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 Updated by: Levi Levitt

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.

Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
They are caused by a symbiotic bacteria which benefits the plant by fixing atmospheric nitrogen (which the plant needs to make proteins).
nitrogen fixing bacteria fix or attach atmospheric nitrogen in soil or make it easily avialable to the plants as plants need nitrogen as one of their macronutrient element for their growth.
