Question

quiz
question 4 of 10
during nitrification, ______.
choose one option
a atmospheric nitrogen is converted into ammonia
b ammonia is combined with oxygen
c proteins are converted into ammonia
d plants take up nitrogen compounds

Explanation:

To solve this, we analyze each option based on the process of nitrification:

• Option A: Converting atmospheric nitrogen to ammonia is nitrogen fixation, not nitrification.
• Option B: Nitrification involves the oxidation of ammonia (or ammonium) to nitrites and then nitrates, which requires combining ammonia with oxygen. This matches the nitrification process.
• Option C: Converting proteins to ammonia is ammonification, not nitrification.
• Option D: Plants taking up nitrogen compounds is assimilation, not nitrification.

Answer:

B. ammonia is combined with oxygen
