Nitrifying bacteria convert to . nitrogen gas ammoniumb. nitrogen gas nitratesc. ammonium nitritesd. nitrates nitrogen gase. ammonium nitrogen gas

c.ammonium ... nitrites is the correct answer.

Explanation:

Nitrifying bacteria convert ammonium to nitrites and this process is called Nitrification.

Nitrification is a naturally occurring process by a specialized type of bacteria(nitrifying bacteria)

Nitrifying bacteria are Nitrosococcus, Nitrococcus, Nitrosomonas, and Nitrobacter.

The conversion of ammonium to nitrites is done by Nitrosomononas bacteria and it a complex process that needs oxygen, protein, and enzymes such as ammonia monooxygenase, hydroxylamine oxidoreductase.

the answer would be d

. ph changes the ability of them he enzyme to dissolve in water.
