Our atmosphere has 78% nitrogen gas. Nitrogen is a critical limiting element for plant growth and production. It cannot be taken directly. Certain bacteria can fix nitrogen from the atmosphere. Which of the following are these?

The correct option is D All
of the above
Biological nitrogen fixation (BNF is carried out by a specialized group of prokaryotes).These organisms utilize the enzyme nitrogenase to catalyze the conversion of atmospheric nitrogen (N2) to ammonia (NH3). Plants can readily assimilate NH3 to produce the aforementioned nitrogenous biomolecules.These prokaryotes include aquatic organisms, such as cyanobacteria(Blue green algae), free-living soil bacteria, such as Azotobacter, bacteria that form associative relationships with plants, such as Azospirillum and most importantly, bacteria, such as Rhizobium.
