Correct answer: by consuming plants and other organisms.
Explanation:
- Animals obtain nitrogen mainly by eating plants or other animals (proteins, nucleic acids, and other N-containing compounds in their food).
- Hosting nitrogen-fixing bacteria: rare exceptions exist (e.g., some termites and a few other animals host N-fixing symbionts), but this is not the typical route for most animals.
- Drinking water high in nitrogen: drinking water may contain dissolved nitrate or ammonium, but it is not a primary or reliable source of nitrogen for animals.
- Absorbing it from the atmosphere: animals cannot directly use atmospheric N2; only certain bacteria and archaea can fix N2 into bioavailable forms.
