Rhizobium

Vedclass · Answer

(A) Nitrogen fixation is the process of converting atmospheric nitrogen $(N_2)$ into ammonia $(NH_3)$,which can be utilized by plants. $Rhizobium$,$Azospirillum$,and $Azotobacter$ are all well-known nitrogen-fixing bacteria. However,in the context of multiple-choice questions where one must identify the most representative answer or if the question implies a single choice among options that are all correct,it is important to note that $Rhizobium$ is a symbiotic nitrogen fixer,while $Azospirillum$ and $Azotobacter$ are free-living nitrogen fixers. Since $Rhizobium$,$Azospirillum$,and $Azotobacter$ are all nitrogen fixers,this question is technically flawed as it contains multiple correct options. Assuming the question asks for a common example,$Rhizobium$ is the most classic example taught in textbooks.
