An energy pyramid, also called a trophic pyramid or an ecological pyramid, is a graphical representation that shows the flow of energy at each trophic level in an ecosystem. The width of each bar represents the available energy units within each trophic level. The height is always the same. The energy flow moves through human evolution. Human evolution is the long-term process of change in which humans evolved from ape-like ancestors. Scientific evidence shows that the physical and behavioral traits common to all humans come from ape-like ancestors and developed over a period of about six million years. One of the earliest defining human traits, bipedalism ,
