Vedclass · Answer

(A) Biofertilisers are organisms that enrich the nutrient quality of the soil. Main sources of biofertilisers are bacteria,fungi,and cyanobacteria. $Rhizobium$ is a symbiotic nitrogen-fixing bacterium found in the root nodules of leguminous plants. Other nitrogen-fixing bacteria include $Azospirillum$ and $Azotobacter$. Blue-green algae (cyanobacteria) like $Anabaena$,$Nostoc$,and $Oscillatoria$ also fix atmospheric nitrogen. Mycorrhiza is a symbiotic association between fungi (e.g.,$Glomus$) and roots of higher plants,which helps in phosphorus absorption. Therefore,the correct group includes Blue-green algae,$Rhizobium$,other nitrogen-fixing bacteria,and mycorrhiza.
