The diagram above shows a pyramid of numbers for a jack pine forest community. the number of producers is much lower than those of the primary consumers. how can this be? a) the jack pine level of the pyramid represents the amount of energy produced by the trees, not the number of trees. b) the biomass of trees is much greater than smaller producers, like grasses and shrubs. one tree can support many primary consumers. c) the jack pines, the autotrophs, would typically have the highest number of organisms with each level above it containing roughly 90% less. d) the pyramid represents the size of the organisms; in this case, the jack pine tree. the pyramid does not represent the comparative number of organisms.
