Nitrogen-Fixing bacteria. aka Rhizobium
Bacteria are the only organisms that can convert nitrogen into a usable form. Diazotroph or nitrogen-fixing bacteria are types of bacteria that perform this ability.
Nitrogen gas (N2) is converted by nitrogen-fixing bacteria that live in the root nodules of Legumes into NH3.
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.
Plants need nitrogen to grow. They are surrounded by nitrogen in the air, but it is not in a form the plants can use. Nitrogen fixing bacteria on the roots of the plant convert (fix) the airborne nitrogen to a form the plants can use to grow.
Nitrogen-Fixing bacteria. aka Rhizobium
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.
animals dont really need nitrogen but for plants, they need nitrogen and they get nitrogen usually in the form of nitrates or bacteria protein, by the work of nitrifying bacteria, putrefying bacteria and nitrogen fixing bacteria

the answer is nitrogen fixation

Actually nitrogen exist in the atmosphere in dinitrogen (N2) form and cannot be utilized directly. As such bacteria help in converting atmospheric nitrogen into ammonia which then can be used by the plants.
