EVERYDAY SCIENCE

Detailed explanation-1: -The bacteria that we are talking about are called nitrosomonas and nitrobacter. Nitrobacter turns nitrites into nitrates; nitrosomonas transform ammonia to nitrites.

Detailed explanation-2: -It is becoming clear that denitrifying fungi, nitrifying archaea, anammox bacteria, aerobic denitrifying bacteria and heterotrophic nitrifying microorganisms are key players in the nitrogen cycle.

Detailed explanation-3: -Rhizobium bacteria are soil microbes that can transform atmospheric nitrogen into a dissolved compound. Rhizobium bacteria are found in the root nodules of woody plants. The rhizobium plays a major role in the nitrogen cycle as well as ecosystem services.

Detailed explanation-4: -Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby breaking the tough triple bond of molecular nitrogen. Such organisms are called “diazotrophs".
