  • 1. Feeding Relationship When organisms of an ecosystem interact by eating each other
  • 2. Your Challenge
    • Carefully read organism cards
    • Organize cards on the table showing feeding relationships
      • Use arrows to show relationship
      • If organisms is involved in more than one feeding relationship, all the relationships should be indicated with arrows
  • 3. Arrow points away from the thing being eaten because the food value of the fly is going into the spider.
  • 4. Food Chain
    • The path that food takes from one organism to another organism
  • 5. Planktonic Algae Brine Shrimp California Gull Coyote Sample Food Chain What do we do about organisms that are eaten by many organisms?
  • 6. Food Web
    • Shows ALL the feeding relationships in an ecosystem
  • 7. Producers
    • Members of the food web that make their own food
    • Producers produce the food that is used in an ecosystem
  • 8. Consumer
    • Organisms that eat other organisms
    • 1 st level or primary consumer eats producers
    • Secondary consumers eat primary consumers
  • 9. Decomposer
    • Break down and consume dead organisms
    • Everything that is not eaten by a consumer is eventually eaten by decomposers
  • 10. 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
  • 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

    • What if the brine shrimp no longer existed at Mono Lake? Predict what would happen to the producers, consumers and decomposers in the ecosystem.
