1. Oceans : Zones, Ecosystems and Resources Oceans : Zones, Ecosystems and Resources How is the ocean divided? Describe different habitats with in the ocean. What resources do the oceans provide? How do organisms in the oceans interact with each other?

2. What resources do Oceans provide us? Resources 1.Food/ Seafood 2.Natural Resources- Metals, Salt, Water, Oil, 3.Transportation- Shipping of goods and people 4.Tourism 5.Climate buffer 6.Oxygen Examples

3. How does the ocean buffer the climate? Currents help to move warm water to the poles and cold water to the equator. The currents warm or cool the air influencing the climate in the particular area.

4. What are the Ocean’s Depth Zones? Surface Zone-  between 0 to 200 meters. Transition zone-  from 200 – 1000 meters. Deep zone-  from 1000 meters to the ocean’s bottom.

5. What and where are the Ocean’s Zones? 1. Intertidal zone-This zone refers to the area between the highest high tide and the lowest low tide. 2. Neretic zone- Shallow waters over the continental shelf. 3. Oceanic zone- waters beyond the continental shelf.

6. Where do most organisms live in the ocean? http://library.thinkquest.org/04oct/01590/intro/ocean.jpg

7. How would you describe the Intertidal Zone? Organisms that live in this zone must be tolerant of changes in the environment. Organisms must be able to withstand changes in temperature, salinity and exposure to air. http://www.georgiastrait.org/files/share/0310-adjusted.jpg http://www.teachersdomain.org/resources/tdc02/sci/life/eco/intertidal/ assets/tdc02_vid_intertidal/tdc02_vid_intertidal_l.jpg

8. Describe two habitats found in the Intertidal Zone. Tide Pools 1.These are area’s where water remains in depressions during low tide. 2.Organisms must withstand changes in temperature and salinity. 3.Organisms include sea stars, sea urchins, and mussels. Estuaries 1.These are coastal inlets or bays where freshwater from rivers meet the saltwater from the ocean. 2.This type of habitat includes mangrove swamps and salt marshes.

11. Ocean Life- p. 189- 190 Ocean Life can be found from the bottom of the ocean to the surface.

12. How are organisms classified in the ocean? Where they live? Three Classifications Benthos (benthic) organisms live on the ocean floor. Nekton are free swimming and live through out the water column. Plankton are microscopic organisms

13. Can you classify each of these organisms? Star fish Microscopic organisms Whale Shark Jelly Fish Clown fish Sea Urchin A. B. C. D. E. F.

14. Making your own Food Web We are going to create a food web for 4 different habitats (po= polar ocean, cr= coral reef, hv= hydrothermal vent, and kf= Kelp Forest) Create a food web for each habitat on your board by: Draw an arrow to what eats it. (Where the energy is going?) Label each organism as a producer, primary consumer, or secondary consumer. For extra credit tell me whether each organism is benthos, nekton, or plankton.

15. Ocean’s Zones and Habitats Chapter 5 Sections 1,2,3,4,5 Describe the different habitats organisms live with in the ocean. Explain why there are so many varieties of organisms within the oceans habitats.

16. The Neretic and Open Ocean Zones Chapter 5, Section 4

17. What are conditions like in the Neretic Zone? It is home to a variety of different organisms. There is plenty of sunlight and nutrients in the water. Nutrients are washed from the land into the oceans from rivers and estuaries.

18. Describe two habitats found in the Neretic Zone. Coral Reefs 1.They make up colonies of small coral animals and algae. 2.They are home to a diverse number of organisms such as fish, anemones, and starfish. 3.They can be found in warm shallow, tropical waters. 4.Found on continental shelves and around volcanic islands. Kelp forests 1.They are found in cold Neretic waters along the Pacific Coast where the floor is rocky. 2.They contain kelp which are large algae anchored to the ocean floor. 3.They provide food and shelter to organisms such as sea urchins, sea otters, and other organisms.

19. Coral Reefs http://earthobservatory.nasa.gov/Study/Paleoclimatology_CloseU p/Images/coral_reef.jpg http://www.oceanblueeducation.com/OBE%20We bsite/HOME/Images/OBE%20website/Programs/P rogram%205.jpg

20. Kelp Forests

21. What are the conditions like in the Open Ocean? The Open Ocean contains few nutrients and a small amount of sunlight. Upwellings- bottom currents that bring nutrients up to the surface. Algae in the surface zone is the main food supply for organisms. http://ricksaphire.com/Photos/pl ankton.jpg

22. Describe two habitats found in the Open Ocean Zone. Deep Zone 1.The water is cold, dark and more harsh than the transition zone. 2.May organisms have adapted to the dark by producing their own light– called bioluminescence. 3.Food Supply is limited. Hydrothermal Vents 1.This is an area where hot water rises from cracks in the oceans floor. 2.They support a variety of unusual organisms. 3.The basis of this food web is bacteria, Bacteria is a food source for many of the organisms that live near these hydrothermal vents.

23. Deep Ocean Creatures- What do they have in common? http://www.extremescience.com/images/Warty- AnglerGlow.jpg http://www.deepseaphotography.com/images/pics/d eep_sea_fish_head.jpg

24. Hydrothermal Vents- Where are they? http://www.bact.wisc.edu/themicrobialworld/Hydrothermal_ vent.jpg http://www.mbari.org/molecular/images/map2.gif

25. Aquatic Food Webs Producers- produce their own food/ energy. Consumers- consume their energy. Primary Consumers- eat producers Secondary Consumers- Eat primary consumers
