Identify the conversion which represents nitrification.
A - Nitrite to nitrate to nitrogen to ammonia
B - Nitrate to nitrite to ammonia to nitrogen
C - Nitrogen to ammonia to nitrite to nitrate
D - Ammonia to nitrate to nitrite to nitrogen
Answer: C - Nitrogen to ammonia to nitrite to nitrate
N2 -> NH3 -> NO2- -> NO3-
NITRIFICATION doesn;t really change the amount of available nitrogen in the environment because plants and other producers can use nitrite and nitrate as sources of nitrogen, it just changes the oxidation state
