Each trophic level has a certain mass of living material at a particular time called as the standing crop. The standing crop is measured as the mass of living organism (biomass) or the number in a unit area. The biomass of a species is expressed in terms of fresh weight or dry weight. Measurement of biomass in terms of dry weight is more accurate.
Primary production is defined as the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis.
