Remembering that each gram of dry biomass is equivalent to kcal of energy, do the following calculations: a. b. How much energy (in kcal) is found in 10 plants that are 7 days old? c. 2. You will calculate the flow of energy from plants (producers) to butterfly larvae (primary consumers). These calculations will include an estimate of (a) secondary productivity, which would be the amount of biomass added to the larvae and therefore available to the next trophic level, and (b) the amount of energy lost to cellular respiration.
