WebOn average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers. Put another way, net productivity usually drops by a factor of ten from one trophic level to the next. WebBiomass is mass per unit area or volume. The value at the end of the dry mass experiment will be given as something like kg per unit area, or kg per unit volume. We can make a pyramid of biomass. We can measure the …
