17. Living things use energy! Living things are divided groups by how they get their energy. • Producers: gets energy from sunlight • Consumers: gets energy from other things • Herbivore: eats only plants • Carnivore: eats only animals • Omnivore: eats plants and animals • Decomposers: get energy from dead things

18. Living things use energy! • Food Chain - shows energy flow from one organism to another

19. Living things use energy! • Food Webs – interconnecting food chains in an ecosystem

21. Living things use energy! • Energy Pyramid – a triangular diagram that shows the loss of energy as it moves between organisms In an energy pyramid, a producer is ALWAYS on the bottom, with a predator on top.
