The answer is nitrogen-fixing bacteria.
<span>Plants
are not able to directly use atmospheric nitrogen. It must be converted into different

ammonium. In the process of assimilation, plants incorporate
ammonium into proteins.</span>
Some legumes have a symbiotic relationship with bacteria that
live in their root system. These bacteria are called Rhizobia and have
the ability of nitrogen-fixation.
