1.	Question : Reaction carried out by N_2 fixing microbes include. (a) 2NH_3+3O_2 to 2NO_2^(-)+2H^(+)+2H_2O……..(i) (b) 2NO_2+O_2 to 2NO_3……….(ii) Which of the following statements about these equations is not true?
Answer» Step (i) is CARRIED out by Nitrosomonas or Nitrococcus Step (II) is carried out by Nitrobacter Both steps (i) and (ii) can be called nitrification BACTERIA carrying out these steps are usually photoautotrophs Solution :Bacteria carrying out these steps are usually photoautotrophs
