344727 Statement A :
Net primary productivity plus respiration losses \((\mathrm{R})\), is the gross primary productivity (GPP).
Statement B :
Net primary productivity is the available biomass for the consumption to autotrophs.

344728 Statement A :
Primary productivity is expressed in terms of weight \({\rm{(g}}{{\rm{m}}^{{\rm{ - 3}}}}{\rm{)}}\) or energy \({\rm{(kcal}}\,{{\rm{m}}^{{\rm{ - 3}}}}{\rm{)}}\)
Statement B :
Productivity is expressed in terms of \({\rm{g}}{{\rm{m}}^{{\rm{ - 2}}}}\,\,{\rm{y}}{{\rm{r}}^{{\rm{ - 1}}}}\,\,{\rm{or}}\,\,{\rm{(kcal}}\,{{\rm{m}}^{{\rm{ - 2}}}}{\rm{)}}\,{\rm{y}}{{\rm{r}}^{{\rm{ - 1}}}}\) to compare the productivity of different ecosystems.

344729 The rate of biomass production is called productivity it may be primary or secondary productivity. Primary productivity does not depends on :-
