Vedclass · Answer

(D) Biofertilizers are organisms that enrich the nutrient quality of the soil. $1$. Bacteria: Many bacteria like $Rhizobium$ (in root nodules of legumes),$Azospirillum$,and $Azotobacter$ fix atmospheric nitrogen. $2$. Fungi: Many members of the genus $Glomus$ form mycorrhiza,which absorbs phosphorus from the soil and passes it to the plant. $3$. Cyanobacteria: Many cyanobacteria like $Anabaena$,$Nostoc$,and $Oscillatoria$ are autotrophic microbes that fix atmospheric nitrogen,especially in paddy fields. Since all three groups act as biofertilizers,the correct answer is $D$.
