Vedclass · Answer

(D) The reactions provided represent the process of nitrification,which is the conversion of ammonia into nitrates.Step $I$ $(2 NH_{3} + 3 O_{2} \rightarrow 2 NO_{2}^{-} + 2 H^{+} + 2 H_{2} O)$ is performed by bacteria such as $Nitrosomonas$ or $Nitrococcus$.Step $II$ $(2 NO_{2}^{-} + O_{2} \rightarrow 2 NO_{3}^{-})$ is performed by $Nitrobacter$.Both steps together are collectively known as nitrification.The bacteria involved in these processes are chemoautotrophs,not photoautotrophs,as they obtain energy by oxidizing inorganic substances rather than using light energy. Therefore,the statement that they are photoautotrophs is incorrect.
