Correct Answer: Ammonia


Solution : The correct answer is Ammonia .

Chemically, ammonia has one atom of nitrogen and three atoms of hydrogen. It is chemically abbreviated as NH 3 . So, it does not contain any oxygen atoms. Ammonia is a colourless gas with a sharp, pungent, and suffocating smell. Ammonification is the process in the nitrogen cycle in which various bacteria, and prokaryotes disintegrate the nucleic acids present in dead, and decaying matter, and release ammonia in the soil.
