Transcript

  • 1. Biology I: Energy Flow Through an Ecosystem (part 1) Producers, Consumers, Decomposers copyright cmassengale
  • 2.
    • Agenda – Mon., Oct. 3, 2011
    • Warm-Up
    • Lesson
    • Classifying Activity (Wrap-Up)
    • Missing Work/Quiz
  • 3. Today’s Objectives
    • I will explore energy flow within an
    • ecosystem.
    • I will define: producer, primary
    • consumer, secondary consumer,
    • tertiary consumer, and decomposer.
    • I will classify producers, consumers,
    • and decomposers.
  • 4. Warm-Up
    • Write three goals you hope to
    • accomplish this week in Biology.
    • Describe three ways you will go about
    • accomplishing these goals.
  • 5. copyright cmassengale The flow of energy begins with the SUN through a process called Photosynthesis.
  • 6.
    • Photosynthesis
    • Chemical reaction where green plants use water & carbon dioxide to make glucose .
    • ENERGY is stored in glucose
    copyright cmassengale
  • 7. PRODUCERS are organisms that can make their own food by carrying out photosynthesis. copyright cmassengale
  • 8. Examples of producers are: plants, algae, and some bacteria Producers use most of the energy that they make for themselves. copyright cmassengale
  • 9. The energy that is not used by producers can be passed on to organisms that cannot make their own food. copyright cmassengale
  • 10. CONSUMERS are organisms that cannot make their own food. They obtain energy by eating other organisms. copyright cmassengale
  • 11. THREE TYPES OF CONSUMER
    • Primary Consumers
    • Secondary Consumers
    • Tertiary Consumers
    copyright cmassengale
  • 12. Primary Consumers are consumers that eat producers to get energy.
    • Examples include plant-eaters such as grasshoppers .
    copyright cmassengale
  • 13. Secondary Consumers are consumers that feed on primary consumers to get energy.
    • Examples include frogs, cats, and birds.
    copyright cmassengale
  • 14. Tertiary consumers are consumers that feed on secondary consumers to get energy .
    • Examples include snakes, hawks, and people.
    copyright cmassengale
  • 15.
    • Decomposers
    copyright cmassengale Decomposers get energy by breaking down dead organisms. Examples include most fungi and many types of bacteria. They return chemicals to the environment .
  • 16. CLASSIFY THE FOLLOWING PICTURES, DESCRIPTIONS, AND SCENARIOS AS: PRODUCER PRIMARY CONSUMER SECONDARY CONSUMER TERTIARY CONSUMER DECOMPOSER copyright cmassengale
  • 17.
    • Organisms that create their own energy by carrying out photosynthesis
    copyright cmassengale
  • 18. copyright cmassengale
  • 19.
    • Frogs commonly eat grasshoppers.
    • The frogs are __________ consumers.
    copyright cmassengale
  • 20.
    • Organisms that break down dead organisms and return the chemicals to the environment
    copyright cmassengale
  • 21. copyright cmassengale
  • 22.
    • A snake eats a frog that ate several grasshoppers.
    • The snake is a __________ consumer.
    copyright cmassengale
  • 23.
    • An organism that fed on another organism that ate a producer.
    copyright cmassengale
  • 24. copyright cmassengale
  • 25.
    • A hawk eats a snake that ate a frog that ate several grasshoppers.
    • The hawk is a __________ consumer.
    copyright cmassengale
  • 26.
    • Organisms that eat only producers.
