Best Answer: nitrogen fixation: turn N2 to a absorb-able form or simply turning them to NH4+.. N2 is converted to NH4+ by Rhizobium (this is nitrogen fixing) NH4+ to NO3- Nitrosomonas then NO3- is converted to NO2- by Nitrobactor (They are nitrifying bacteria NOT NITROGEN FIXING). (only rhizobium is nitrogen fixing). Source(s): my brain .. i'm not a chemist :p ..
