- One of the lessons from a pyramid of production is that _____. A) eating grain-fed beef is an inefficient means of obtaining the energy trapped by photosynthesis B) the energy lost as heat or lost in cellular respiration is 10% of the available energy of each trophic level C) only one-half of the energy in one trophic level is passed on to the next level D) most of the energy from one trophic level is incorporated into the biomass of the next level E) production efficiency is highest for primary consumersAt which point in the trophic pyramid is the greatest arount (not percentage) of energy lost? A) Between the primary producers and the primary consumers B) Between the primary consumers and the secondary consumers C)Between the secondary consumers and the tertiary consumers D) Between the secondary consumers and the primary producers1) A scientist finds that the gross primary productivity of the grasslands of the central United States is 55 g / m2 / year.
