Lesson Transcript. Instructor: Meredith Mikell. When organisms eat other organisms, energy is transferred. An energy pyramid can be used to diagram this flow of metabolic energy. Here we will examine the definition of an energy pyramid, look at some examples, and finish with a brief quiz.esson Transcript. Instructor: Meredith Mikell.
