Explanation:

Nitrogen fixation is a biological process where atmospheric nitrogen (\(N_2\)) is converted into ammonia (\(NH_3\)) or other nitrogen - containing compounds that plants can use. Certain bacteria, such as Rhizobium (which forms symbiotic relationships with legume plants) and free - living bacteria like Azotobacter, have the enzyme nitrogenase that enables them to perform nitrogen fixation. Fungi do not have the ability to fix nitrogen. Plants, while they can take up fixed nitrogen compounds (such as nitrates), they cannot fix atmospheric nitrogen on their own.

B. Bacteria
