fixation is the process of

• conversion of N2 to forms that can be used to synthesize inorganic nitrogen compounds

• conversion of Co2 to forms that can be used to synthesize organic carbonic compounds

• conversion of N2 to forms that can be used to synthesize organic nitrogen compounds

• conversion of H2O to forms that can be used to synthesize organic aqueous compounds
