  • Plankton Station

    1. 1. INLAND SEAS EDUCATION ASSOCIATION “ Protecting the Great Lakes through Education” Plankton Station
    2. 2. Plankton Station Learning Objectives <ul><li>Identify the collection device used to sample plankton. </li></ul><ul><li>Define phytoplankton as suspended plants & zooplankton as suspended animals. </li></ul><ul><li>Recognize plankton as the basis of the aquatic food web. </li></ul><ul><li>Describe the trophic (feeding) relationships among phytoplankton, zooplankton, & fish. </li></ul><ul><li>Identify zooplankton seen on the video monitor & record their findings. </li></ul>Students will be able to:
    3. 3. Plankton <ul><li>Plankton are microscopic plants & animals that are free-floating or suspended in the water </li></ul>
    4. 4. Plankton Plant plankton Animal plankton = Phytoplankton = Zooplankton
    5. 5. Plankton <ul><li>Plankton are the basis of the aquatic food web </li></ul>
    6. 6. What is a Food Web? <ul><li>A food web describes the feeding relationships between different organisms </li></ul>
    7. 7. Feeding Relationships <ul><li>Producers: organisms that produce their own food through photosynthesis using sunlight & nutrients </li></ul><ul><li>Consumers: organisms that cannot produce their own food (need to consume another organism to obtain energy) </li></ul><ul><li>Decomposers: organisms that break down organic material </li></ul>
    8. 8. The Great Lakes Food Web SUN Zooplankton Large Fish (Piscivores) Phytoplankton Forage Fish Benthos Detritus
    9. 10. Contaminants in the Great Lakes Food Web Source: EPA Great Lakes National Program Office
    10. 11. Bioaccumulation <ul><li>Bioaccumulation refers to the accumulation of contaminants in the tissues of organisms </li></ul><ul><li>Many contaminants are hydrophobic (they prefer to be in the lipids/fats of an organism rather than in water) & are taken up in the fatty tissues of organisms </li></ul>
    11. 12. Bioconcentration Source: EPA Great Lakes National Program Office
    12. 14. Diel vertical migration Shallow waters at night Deep waters during the day … in response to changing light intensity <ul><li>Why? </li></ul><ul><ul><li>Metabloic advantage </li></ul></ul><ul><ul><li>Predator avoidance </li></ul></ul>
    13. 20. Logistics <ul><li>Check to make sure the micro-video system is working </li></ul><ul><li>Begin by discussing how the plankton were collected, where plankton fit into the food web, etc. </li></ul><ul><li>Students put several drops of the sample on a petri dish (the smaller the better) </li></ul><ul><li>Since the boat & plankton are moving & this station is below deck, students may get seasick </li></ul><ul><ul><li>Let the lead instructor know & they will take the student on deck for a break </li></ul></ul>
