Pyramid. Computer illustration of a pyramid containing arrows, which could represent any system in which there is a hierarchy. Fewer arrows are present on each higher level. Several systems have an input at a low level, with sequentially fewer and more important systems on each higher level. This pattern is seen in many places, including food chains in natural ecosystems, information management and in all types of social and business interactions.
