A) nitrogen fixers; ammonia (NH₃) to nitrite ions (NO₂^-); nitrite to nitrate (NO₃^-) B) denitrifiers; ammonia (NH₃) to nitrite ions (NO₂^-); nitrite to nitrate (NO₃^-) C) denitrifiers; nitrite to nitrate (NO₃^-); ammonia (NH₃) to nitrite ions (NO₂^-) D) nitrifiers; nitrite to nitrate (NO₃^-); ammonia (NH₃) to nitrite ions (NO₂^-) E) nitrifiers; ammonia (NH₃) to nitrite ions (NO₂^-); nitrite to nitrate (NO₃^-)

Question

Quizplus · Accepted Answer

The question describes the process of nitrification, which is carried out by chemoautotrophic bacteria called nitrifiers. The two-step process involves the conversion of ammonia (NH3) to nitrite ions (NO2-) by Nitrosomonas and Nitrosococcus, followed by the conversion of nitrite ions (NO2-) to nitrate (NO3-) by Nitrobacter. Nitrate is the most usable form of nitrogen for plants. Therefore, the correct answer is E, which describes the process of nitrification.
