344755 Primary production is

1 Expressed in terms of weight \(\left(\mathrm{gm}^{-2}\right)\) or energy \(\left( {{\rm{kcal}}\,{{\rm{m}}^{{\rm{ - 2}}}}} \right)\)
2 The amount of biomas or organic matter produced per unit area over a time period by plants during photosynthesis
3 The amount of inorganic matter produced per unit area over a time period by plants during photosynthesis
4 Both 1 and 2
