Verified step by step guidance

Understand the role of denitrifying bacteria: These bacteria are involved in the nitrogen cycle, specifically in the process of denitrification, where they convert nitrates (NO₃⁻) and nitrites (NO₂⁻) into nitrogen gas (N₂).

Recognize the chemical transformation: Denitrification is a reduction process where nitrates and nitrites are reduced to nitrogen gas, which is released into the atmosphere.

Identify the products of denitrification: The primary product of this process is nitrogen gas (N₂), although small amounts of nitrous oxide (N₂O) can also be produced as an intermediate.

Differentiate between the options: Ammonia (NH₃) and nitric acid (HNO₃) are not products of denitrification. Ammonia is typically produced in the process of ammonification, while nitric acid is not directly involved in this bacterial process.

Conclude with the correct product: Based on the understanding of denitrification, the correct conversion product of nitrates and nitrites by denitrifying bacteria is nitrogen gas (N₂).
