3. Factors Effecting the Composition of Marine Waters AirAir –The levels of oxygen (O 2 ) and carbon dioxide (CO 2 ) in the water are greatly effected by the air Rivers and Runoff from LandRivers and Runoff from Land –add minerals and sediment DisastersDisasters –Hurricanes, typhoons, and cyclones weather and erode the coastal regions washing sediments into the ocean –Human activities

4. Components of the Marine Biome Abiotic (nonliving)Abiotic (nonliving) –Water –Sunlight/darkness –Minerals –Dissolved gases Biotic (living)Biotic (living) –Producers –Consumers –Decomposers

5. Levels of Light in the Ocean Photic zonePhotic zone –Light fills the water at this level Twilight zoneTwilight zone –Transition zone between light and absolute darkness Aphotic zoneAphotic zone –Depths where no sunlight exists (Click image) Aphotic Zone

6. Eat the producers - herbivoresEat the producers - herbivores –Sea urchins – eat kelp –Sea butterflies – feed on phytoplankton –Parrot fish – eat algae Primary Consumers

7. Eat the primary consumers – carnivores or omnivoresEat the primary consumers – carnivores or omnivores –Jelly fish – eat small fish –Clown fish – eat small invertebrates –Sea otters – eat sea urchins Secondary Consumers

8. Tertiary Consumers Eat the secondary consumersEat the secondary consumers –Polar bears – eat seals, walrus, and beluga whales –Great White sharks – eat dolphins, sharks, whales, sea lions, sea turtles and sea birds –Bull sharks – eat dolphins, rays, sea turtles and sea birds

9. Decomposers Filter Feeders – remove dead materials floating in the waterFilter Feeders – remove dead materials floating in the water –Ex. Tube worms and anemones Bottom Feeders – break down dead materials that has made its way to the ocean floorBottom Feeders – break down dead materials that has made its way to the ocean floor –Ex. Sea Cucumbers and Star Fish
