Crystal Cove Science

Discover the complex relationships within the ocean ecosystem, including the food chain and decomposition. Learn why sharks are at the top of the pyramid and why there are fewer sharks compared to other fish. Explore the energy pyramid and how energy is lost at each level. Understand the role of decomposers in breaking down dead animals and plants. Engage in a decomposition experiment using yeast and a banana. Classify animals as vertebrates or invertebrates.

  1. Crystal Cove Science 2-9-17

  2. Do you notice any relationships? • ocean ecosystem

  3. producers Food Chain A series of events in which one organism eats another The top consumer eats the secondary consumers, which eat the primary consumers, which eat the producers Altering any level of the chain affects all other levels Top consumer

  4. Food Web • In Nature, ecosystems are much more complicated than a food chain • cave 3:30-6:30

  5. 1)Why are sharks at the top of the pyramid2) Why are there less sharks than the other fish?

  6. Energy Is lost at every level of the food chain (as heat during the life of the organism)it takes a lot of producers to feed one consumer

  7. Energy pyramid A diagram showing energy available at each level of the food chain The wider the level, the more energy available Most energy is available at the bottom level producer level (energy is lost as we go up)

  8. Do dead plants and animals go to waste? • decomposers

  9. decomposers Bacteria and other creatures that break down dead animals and plants for food Dead decomposers fertilize the soil for producers to grow again The circle continues

  10. Decomposition bag experiment • Yeast • Banana • Bag • Watch for 1 week, monitor decomposition of banana with the yeast

  11. Extra bit • invertebrates • large vertebrate

  12. Classification of Animals • Vertebrates- animals with a spinal cord • Invertebrates- animals without a spinal cord
