Question

question 4 of 10
which are products of nitrogen fixation?
a. phosphorus, nitrates, nodules
b. nodules, roots, fertilizer
c. oxygen, carbon, water
d. ammonia, nitrates, nitrites

Explanation:

Nitrogen fixation is the process of converting atmospheric nitrogen (\(N_2\)) into ammonia (\(NH_3\)). Ammonia can then be further converted into nitrates (\(NO_3^-\)) and nitrites (\(NO_2^-\)) through nitrification. These compounds are essential for plant growth as they are forms of nitrogen that plants can absorb. Option A includes phosphorus (not a product of nitrogen fixation). Option B has nodules (structures where nitrogen - fixing bacteria live, not a chemical product) and roots/fertilizer (not relevant). Option C has oxygen, carbon, water (not related to nitrogen fixation products). So, the correct products are ammonia, nitrates, and nitrites as in option D.

Answer:

D. Ammonia, nitrates, nitrites
