  1. Food Chains

  2. Living Things Depend on Each Other

  3. Making and Getting Food • Interact with environment • Why do animals interact with the environment to get their food? • Plants are producers • What is a producer? • An animal is a consumer. • What is a consumer?

  4. Consumers • Animals cannot make their own food. • Animals are consumers. • A consumer is a living thing that eats other living things. • Consumers are grouped by what they eat.

  5. Herbivores • What are herbivores?

  6. Carnivores • What are carnivores?

  7. Omnivores • What are omnivores?

  8. Decomposers • What is a decomposer?

  9. Review • How do producers get their food? • How do consumers get their food? • What are the three groups of consumers? • How do decomposers help keep the environment clean? • Which of the following is NOT a consumer? A. bird C. squirrel B. tree D. human

  10. Food and Energy • What is a food chain? Grasshoppers eat grass All plants are producers. Frogs eat grasshoppers. The owl dies and fertilizes the plants. Owls eat frogs

  11. Energy Pyramid • What is an energy pyramid? Animals that are not usually eaten by other animals Animals that eat other animals Plant-eating animals Plants

  12. Review • How does energy get from a producer to a meat-eating consumer? • What kind of living thing is at the top of a food chain? • Where is the most food energy in an energy pyramid found? • What is the source of all the energy on Earth? • Which is passed in a food chain from one living thing to another? A. producers C. sunlight B. animals D. energy

  13. Summary • Plants and animals interact. • Plants are producers. • Animals are consumers. • Decomposers get food by breaking down wastes or dead things. • Living things get their energy from food. • Animals cannot make their own food, so they eat other living things. • A food chain is the flow of food in an ecosystem from one living thing to another. • An energy pyramid show that the amount of usable energy in an ecosystem is less for each higher animal in the food chain.
