Question

In the nitrogen cycle, the bacteria, which change proteins to ammonia, are known as_________________

• A. Bacteria of decay
• B. Denitrifying bacteria
• C. Nitrogen fixing bacteria
• D. Nitrate bacteria

Answer 1

The correct option is A Bacteria of decay

• Ammonification is the process of conversion of organic nitrogen content in the dead and decaying matter to ammonium salts which further undergoes nitrification to get converted into a usable form.
• This breakdown is accomplished by microorganisms (decay bacteria) that utilize dead organic material for energy and produce ammonia and related compounds as a byproduct of their metabolisms.

Therefore, the correct answer is option A.
