Vedclass · Answer

(C) Let's analyze each pair:$1$. $I$. Nitrosomonas: This bacterium converts ammonia to nitrite $(NH_3 \rightarrow NO_2^-)$,not nitrite to nitrate. Thus,this is incorrect.$2$. $II$. Thiobacillus: This bacterium is involved in denitrification,where it converts nitrates back into nitrogen gas $(N_2)$. This is correct.$3$. $III$. Nostoc: This is a cyanobacterium that acts as a free-living nitrogen fixer. This is correct.$4$. $IV$. Azotobacter: This is an aerobic,free-living nitrogen-fixing bacterium,not anaerobic. Thus,this is incorrect.Therefore,the correct pairs are $II$ and $III$.

Column-$I$	Column-$II$
$I$. Nitrosomonas	Nitrite to nitrate
$II$. Thiobacillus	Denitrification
$III$. Nostoc	Free-living nitrogen fixer
$IV$. Azotobacter	Anaerobic nitrogen fixer

Choose the correct pair:
