Any time energy is transferred from one organism to another, some of that energy is lost, mostly in the form of heat. In fact, only about 10% of the energy from an organism at a low trophic level can be transferred to an organism at the next trophic level. Because of this inefficiency, trophic levels always appear as pyramids, with the primary producers forming the base, and the secondary and tertiary consumers forming the apex.
