Vedclass · Answer

(A) $Azolla$ $pinnata$ is a small aquatic fern that has a symbiotic relationship with the nitrogen-fixing cyanobacterium $Anabaena$ $azollae$.This association allows $Azolla$ to fix atmospheric nitrogen,which is then released into the water and soil upon the decomposition of the fern.Because paddy crops require flooded conditions,$Azolla$ grows abundantly in these fields,making it an excellent natural biofertilizer that significantly increases rice yield.
