Define Denitrification .

(a) The equations given below represent the different stages of Nitrogen Cycle in plants. (i) 2NH_(3)^(+)+3O_(2)overset([A])rarr 2NO_(2)^(-)+2H^(+)+2H_(2)O (ii) 2NO_(2)^(-)+O_(2)overset([B])rarr 2NO_(3)^(-) (iii) underset("[Nitrate]")(NO_(3)^(-))overset([C])rarr underset("[Molecular Nitrogen]")(N_(2)) In the above equations [A], [B],[C] indicate the bacteria which is responsible for the reaction. Name them. (b) Define Denitrification. (c) Which enzyme is required for Nitrogen fixation ?
