Can eukaryotes fix nitrogen
WebProkaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria (in the soil and within the root nodules of some plants) convert nitrogen gas in the atmosphere to … Webnitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle. Two kinds of nitrogen-fixing bacteria are recognized. The first kind, the …
