Question

in the nitrogen cycle, the process where ammonia (nh₃) is converted into nitrites (no₂) and nitrates (no₃) is called:
nitrification
nitrogen fixation
denitrification
producer uptake

Explanation:

Nitrification is the biological oxidation of ammonia to nitrites and then to nitrates. Nitrogen fixation converts \(N_2\) to ammonia. Denitrification reduces nitrates to \(N_2\). Producer uptake is plants absorbing nitrates.

Answer:

Nitrification
