Transcript of "Investigation 5 4 2009[1]"

  1. 1. Food Energy Review <ul><li>What is food? </li></ul><ul><li>Why do organisms consume food? </li></ul><ul><li>Where is food used in a food web? </li></ul>
  2. 2. Producer <ul><li>PRODUCES its own food through photosynthesis </li></ul><ul><li>Examples include plants and algae </li></ul>
  3. 3. Primary consumers <ul><li>Eat the producers </li></ul>
  4. 4. Secondary Consumers <ul><li>Eat the primary consumers </li></ul><ul><li>3 rd level consumers eat secondary consumers, 4 th level consumers eat 3 rd level consumers and so on </li></ul>
  5. 5. Decomposers <ul><li>DECOMPOSE things in an ecosystem </li></ul><ul><li>Consume all levels of the food web </li></ul>
  6. 6. DECOMPOSERS PRODUCERS PRIMARY CONSUMERS SECONDARY CONSUMERS THIRD-LEVEL CONSUMERS Planktonic algae Benthic algae Brine Shrimp Brine fly Red-necked phalarope Wilson’s phalarope Eared grebe Caspian tern Snowy plover Coyote California gull
  7. 7. Mono Lake Ecosystem <ul><li>How does energy enter the Mono Lake ecosystem? </li></ul><ul><li>Do migratory birds (gulls, phalaropes, etc) bring energy in or take energy out of the ecosystem? </li></ul>
  8. 8. <ul><li>Algae manufacture food. What happens to the food made by the algae? </li></ul><ul><li>What happens to the energy in algae eaten by the brine shrimp? </li></ul>
  9. 9. Trophic Levels <ul><li>Where does all the energy come from? </li></ul>
  10. 10. Sun Algae Brine shrimp Brine fly California Gull Coyote Decomposer <ul><li>Energy moves through different trophic levels in an Ecosystem, like Mono Lake </li></ul><ul><li>Starts with the sun and ends with the environment </li></ul>Environment
  11. 11. DECOMPOSERS PRODUCERS PRIMARY CONSUMERS SECONDARY CONSUMERS THIRD-LEVEL CONSUMERS Planktonic algae Benthic algae Brine Shrimp Brine fly Red-necked phalarope Wilson’s phalarope Eared grebe Caspian tern Snowy plover Coyote California gull
  12. 12. DECOMPOSERS
  13. 14. Is all the food energy consumed by a primary consumer transferred to the secondary consumer when it is eaten?
  14. 15. 10% Rule <ul><li>Only 10% of the energy consumed at one trophic level is available as food for the next trophic level </li></ul>
  15. 16. Based on the 10% rule, could you have an ecosystem in which there lived 100 kg of algae, 100 kg of brine shrimp, and 100 kg of California gulls?
  16. 17. Reflection pg. 44 <ul><li>Choose an ecosystem </li></ul><ul><li>Create a trophic level pyramid for organisms in that ecosystem. Don’t forget the decomposers! </li></ul>
