  9. Build a Food Web Click on the links below to build a food web: Food Web Build a Food Web Build an Aquatic Food Web Fun with Food Webs

  10. Energy Pyramid • Shows the amounts of energy available at each trophic (nutritional) level of an ecosystem • Producers are at the base – consumers make up the other levels. • The higher in the pyramid, the less energy available Secondary Consumer Primary Consumer
