Rhizobium Bacillus is the bacteria that converts nitrogen gas in the air into ammonia. It plays an important role the nitrogen cycle by fixing nitrogen which is otherwise an inert gas.
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
NO. Nitrogen is a required nutrient for plants but it is obtained from ammonia or nitrates used as fertilizers. Some plants can "fix" (convert nitrogen in the air to an usable form) with the assistance of microorganisms living at the roots.
These bacteria, through the plant, receive elemental nitrogen from the air, and use it to produce ammonia (NH3). This process is called nitrogen fixation. The ammonia can then be converted in to oxides of nitrogen and nitrogen salts, such as nitrites and nitrates, which are used by the host plant and others as nutrients.
Nitrogen is vital to plants (as well as all other life) as it is a key component of chlorophyll, proteins, and DNA. Without nitrogen fixing bacteria, most plants would quickly deplete the limited stores of nitrogen found in the soil in their immediate area. Nitrogen fixing bacteria are able to synthesize ammonia from free nitrogen in the air, and plants can utilize this ammonia in all of their biological processes.

Nitrogen Fixation
Nitrogen-fixing bacteria in nodules on plant roots (legume plants; beans, peas, alfalfa) convert nitrogen in the air (ammonia) to nitrites then nitrates which is then absorbed by plants through their roots.
it is bacteria and lightening or decomposers, not sure. I am doing the same biology homework crap that Ms. elliot signed to all the students over break. i am looking for the same answer i think decomposers is the answer. its the one that makes most sense. :D

Nitrogen-Fixing bacteria. aka Rhizobium
They absorb nitrogen from the air. Then nitrogen-fixing bacteria convert it to a useable form.
Nitrogen fixing bacteria along and on the roots of plants converts gaseous nitrogen into a form that plants can absorb.

You get it every time you take a breath even though you don't need it to survive.
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-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).
