Question

Quizplus · Accepted Answer

Both nitrifying bacteria (Nitrosomonas) and sulfur-oxidizing bacteria are chemoautotrophs, meaning they obtain their energy by oxidizing inorganic compounds. Nitrosomonas oxidizes ammonia to nitrite while sulfur-oxidizing bacteria oxidizes sulfur compounds. This process is used to produce their own organic compounds for growth and reproduction.
