Vedclass · Answer

(A) The process of nitrification involves two steps carried out by specific chemoautotrophic bacteria:$1$. Ammonia $(NH_3)$ is oxidized to nitrite $(NO_2^-)$ by bacteria such as $Nitrosomonas$ and $Nitrosococcus$.$2$. Nitrite $(NO_2^-)$ is further oxidized to nitrate $(NO_3^-)$ by the bacterium $Nitrobacter$.Therefore,the correct sequence is $Nitrosomonas$ for the first step and $Nitrobacter$ for the second step.

Which bacteria are responsible for the conversion of ammonia into nitrite ions and nitrite into nitrate ions,respectively?
