Answer 2

Answer:

Explanation:

Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. ... The bacteria colonize plant cells within root nodules, where they convert atmospheric nitrogen into ammonia using the enzyme nitrogenase and then provide organic nitrogenous compounds such as glutamine or ureides to the plant.
