1. Phytoplankton and Zooplankton

2. Phytoplankton The most important organisms on the planet are……………

3. Phytoplankton Generate 50% of the oxygen that we breath. They are called the plants of the sea. Examples: diatoms, radiolarians, dinoflagellates, foraminifera

4. Ocean water: Under the microscope: What do you see?

5. Phytoplankton: Sustain all marine organisms

6. Where do we find Phytoplankton?

7. Phytoplankton distribution is patchy. Phytoplankton exist Where there is sunlight and nutrients. (red highest Blue lowest)

8. There are no/little Phytoplankton in Tropical Waters Why?: Use the pictures To help answer: http://www.youtube.com/ watch?v=_Ww6BIy3nc0 http://www.youtube.com/ watch?v=_Ww6BIy3nc0

9. Answer: Upwelling is not present in these tropical waters: Upwelling brings nutrients found on the bottom into the top layer where there is plenty of sun.

10. Phytoplankton Blooms Phytoplankton Blooms: Uncontrolled growth of one species of phtoplankton. Called the “Red Tide” “Brown Tide” depending on the species

11. Phytoplankton Blooms Major reasons are, storm water runoff, too many nutrients going into the water from fertilizers, from human activities.

12. Phytoplankton Blooms They produce a toxin that makes them taste bad to fish that would otherwise eat them. Although this chemical can even kill fish, medical experts say it only irritates humans (swimming in). The toxin can build up in shellfish. That’s why tainted shellfish are unsafe and possibly deadly for humans to eat

13. Dinoflagellates of Long Island

14. Zooplankton Zooplankton are heterotrophs “drifters” in the oceans reliant on currents for movement. Can Range in size microscopic to as large as jellyfish

15. Food Chain of Marine Ecosystems phytoplanktonzooplankton???

16. What eats zooplankton Some examples: Blue Whale Basking Shark Manta Ray

17. Zooplankton primary consumers in food chains. They include all the classification of organisms and will be discussed in the other phylum powerpoints. Rotifer; eating phyto plankton

18. Phytoplankton Zooplankton What do they need in order to survive: 1. 2. 3. 4. 5. What do they need in order to survive: 1. 2. 3 4. 5.
