Nitrogen fixation is shown by prokaryotes and not eukaryotes. Comment.

(N/A) $1$. Nitrogen fixation is a biological process exclusively performed by certain prokaryotes because they possess the specialized enzyme complex known as $Nitrogenase$.
$2$. Examples of such prokaryotes include $Rhizobium$,$Anabaena$,and $Nostoc$.
$3$. Eukaryotic organisms lack the genetic machinery to synthesize the $Nitrogenase$ enzyme complex; therefore,they are incapable of performing biological nitrogen fixation independently.
