    1. 1. Food Chains
    2. 2. Plankton Why are they so important?
    3. 3. PLANKTON Comes from the Greek word “ planktos ” which means drifting <ul><li>Plants - Phyto plankton </li></ul><ul><li>Animals – Zoo plankton </li></ul>
    4. 4. PHYTOPLANKTON <ul><li>Float near the surface </li></ul><ul><li>Most can’t swim </li></ul><ul><li>Make their own energy through photosynthesis </li></ul><ul><li>Food for zooplankton </li></ul><ul><li>Beginning of the food chain </li></ul>
    5. 5. PHytoplankton <ul><li>Can change the color of the water </li></ul><ul><li>Large number of Plankton in one area. </li></ul><ul><li>Called a BLOOM </li></ul>
    6. 6. PHytoplankton <ul><li>Where you find lots of plankton: </li></ul><ul><ul><li>Ocean provides large amounts of nutrients </li></ul></ul><ul><li>Where you find little plankton: </li></ul><ul><ul><li>Poisons in the water or </li></ul></ul><ul><ul><li>Changes in water temperature </li></ul></ul><ul><ul><ul><li>colder water has more nutrients </li></ul></ul></ul>
    7. 7. Fishermen <ul><li>Look at ocean color images to find areas rich with phytoplankton </li></ul>
    8. 8. Zooplankton <ul><li>Animals that either don’t swim or are very weak swimmers </li></ul><ul><li>Some are eggs or larva of animals that will one day become nekton (animals that swim freely) </li></ul>
    9. 9. Zooplankton <ul><li>Varying sizes, but some are quite large! </li></ul><ul><li>Zooplankton feast on the phytoplankton… and sometimes other zooplankton ! </li></ul><ul><li>Let’s Create a Plankton </li></ul>
    10. 10. F oo d chain G am e <ul><li>PRODUCERS: </li></ul><ul><ul><li>Phytoplankton </li></ul></ul><ul><li>CONSUMERS: </li></ul><ul><ul><li>1 st - Zooplankton </li></ul></ul><ul><ul><li>2 nd - Nekton </li></ul></ul><ul><ul><li>3 rd - more Nekton </li></ul></ul><ul><li>DECOMPOSERS: </li></ul><ul><ul><li>Primarily bacteria </li></ul></ul>
    11. 11. Food WEBS <ul><li>Have many Food Chains in them </li></ul><ul><li>Can you decide who is a producer, a consumer, and a decomposer ? </li></ul>
