Energy Roles

• Producers an organism that can make its own
  food (plants)
• Consumers organism that gains energy by feeding
  on another organism
• Herbivores eat only plants
• Carnivores eat only animals
• Omnivores eat plants and animals
• Scavengers dead animals
• Decomposers break down wastes and return raw
  materials to the ecosystem (mushrooms, bacteria)

Energy Pyramids

• Shows the amount of energy that moves from one
  feeding level to the next
• Most energy available at the producer level
• Only about 10 of the energy transferred to next
  level
