assuming that your producer level has 3,500,000 kilocalories of energy/area, use the rule 10 percent in energy transfer to calculate the amount of energy available at each consumer level. write those numbers to the right of each trophic level in the pyramid. show your calculations in the space below

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
