Vedclass · Answer

(A) $Rhizobium$ is a symbiotic nitrogen-fixing bacterium that lives in the root nodules of leguminous plants. It possesses the enzyme nitrogenase,which allows it to convert atmospheric molecular nitrogen $(N_2)$ into ammonia $(NH_3)$,a form that can be utilized by the plant for growth and development. Other options like $Spirogyra$ (algae),$Mucor$ (fungi),and $Methanococcus$ (archaea) do not possess the capability to fix atmospheric nitrogen.

Which one of the following can utilize molecular nitrogen $(N_2)$ as a nutrient for growth?
