Question

living bacteria, like nitrosomonas, require which element to survive?
o oxygen
o sulfur

Explanation:

Nitrosomonas is a genus of bacteria involved in nitrification (converting ammonia to nitrite). These bacteria are aerobic, meaning they require oxygen for respiration (using oxygen to break down organic or inorganic compounds for energy). Sulfur is not a primary survival - essential element for Nitrosomonas in the same way oxygen is for their metabolic processes.

Answer:

Oxygen
