Picture Vocabulary Energy Pyramid A diagram that shows the trophic levels of organisms in a food web Tertiary consumer Secondary consumer Primary . carnivores. A carnivore is an animal that gets food from . killing . carnivores have to hunt down and kill other animals they require a large amount of calories. This means that they have to eat many other animals over the course of the year. The bigger the carnivore, the more it has to eat. You should make sure that you have many more herbivores and omnivores than . Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. Tonle. Sap Fishery. Vittoria Elliott.
