Nitrates are made by converting ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). What do you predict the O2 levels in the river will be? High - Nitrate (NO3-) contains more oxygen atoms than ammonia (NH3), so the O2 will be high. Normal - Even though oxygen atoms are added to nitrogen during the nitrogen cycle, the levels of O2 in the water will be normal. Low - The generation of nitrates (NO3-) requires oxygen, so the oxygen levels will be low.
