The conversion of nitrite ($NO_2^-$) to nitrate ($NO_3^-$) during nitrification is catalyzed by:
Show answer and explanation
Correct answer: Nitrobacter
Nitrobacter is a chemoautotroph that oxidizes nitrite into nitrate. This is the second step of nitrification, and the resulting nitrate is the form most easily absorbed by plants.
