Ecosystem energy flow (part 1)

  1. 1. Biology I: Energy Flow Through an Ecosystem (part 1) Producers, Consumers, Decomposers copyright cmassengale
  2. 2. <ul><li>Agenda – Mon., Oct. 3, 2011 </li></ul><ul><li>Warm-Up </li></ul><ul><li>Lesson </li></ul><ul><li>Classifying Activity (Wrap-Up) </li></ul><ul><li>Missing Work/Quiz </li></ul>
  3. 3. Today’s Objectives <ul><li>I will explore energy flow within an </li></ul><ul><li>ecosystem. </li></ul><ul><li>I will define: producer, primary </li></ul><ul><li>consumer, secondary consumer, </li></ul><ul><li>tertiary consumer, and decomposer. </li></ul><ul><li>I will classify producers, consumers, </li></ul><ul><li>and decomposers. </li></ul>
  4. 4. Warm-Up <ul><li>Write three goals you hope to </li></ul><ul><li>accomplish this week in Biology. </li></ul><ul><li>Describe three ways you will go about </li></ul><ul><li>accomplishing these goals. </li></ul>
  5. 5. copyright cmassengale The flow of energy begins with the SUN through a process called Photosynthesis.
  6. 6. <ul><li>Photosynthesis </li></ul><ul><li>Chemical reaction where green plants use water & carbon dioxide to make glucose . </li></ul><ul><li>ENERGY is stored in glucose </li></ul>copyright cmassengale
  7. 7. PRODUCERS are organisms that can make their own food by carrying out photosynthesis. copyright cmassengale
  8. 8. Examples of producers are: plants, algae, and some bacteria Producers use most of the energy that they make for themselves. copyright cmassengale
  9. 9. The energy that is not used by producers can be passed on to organisms that cannot make their own food. copyright cmassengale
  10. 10. CONSUMERS are organisms that cannot make their own food. They obtain energy by eating other organisms. copyright cmassengale
  11. 11. THREE TYPES OF CONSUMER <ul><li>Primary Consumers </li></ul><ul><li>Secondary Consumers </li></ul><ul><li>Tertiary Consumers </li></ul>copyright cmassengale
  12. 12. Primary Consumers are consumers that eat producers to get energy. <ul><li>Examples include plant-eaters such as grasshoppers . </li></ul>copyright cmassengale
  13. 13. Secondary Consumers are consumers that feed on primary consumers to get energy. <ul><li>Examples include frogs, cats, and birds. </li></ul>copyright cmassengale
  14. 14. Tertiary consumers are consumers that feed on secondary consumers to get energy . <ul><li>Examples include snakes, hawks, and people. </li></ul>copyright cmassengale
  15. 15. <ul><li>Decomposers </li></ul>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 .
