Question

Which of the following is true about denitrifying bacteria?

• A. Turn ammonia into NO${}_2$(nitrites)
• B. Turn ammonia into N${}_2$
• C. Turn ammonia into NO${}_3$(nitrates)
• D. Do not use nitrogen in their life cycle
• E. None of the above

Answer 1

The correct option is B Turn ammonia into N${}_2$

Denitrification is the process of conversion of inorganic Nitrogen substances into atmospheric nitrogen.

Ammonia into nitrites of nitrates is known as nitrification.

Denitrifying bacteria perform this process.

So the correct answer is 'Turn ammonia into $N_2$ '
