The correct answer is: B.Ammonia/nitrate.

Explanation:

When animal waste decays, bacteria break down the organic matter, and through various processes in the nitrogen cycle, they produce nitrogen-rich compounds. These compounds are crucial for plant growth. The two main products produced are:

1.Ammonia (NH₃): This is released during ammonification when bacteria decompose proteins and other nitrogen-containing organic compounds from the waste.

2.Nitrate (NO₃⁻): In the process of nitrification, some bacteria convert ammonia to nitrites (NO₂⁻), and then to nitrates (NO₃⁻), which plants readily absorb and use for growth.

Why the other options are incorrect:

A.Carbon dioxide/...
