  • What are the trophic levels in this web? How does it change with removal of keystone species?
  • Can you tell what the non-native invasive species that were introduced are?What happens to biodiversity of this ecosystem over time?
  • Advantages: don’t need a mate and can produce many offspring without expending much energyDisadvantage: no genetic variation so if the ecosystem changes like with introduction of invasive species or removal of keystone species; consequences could be deadly to all( weakness is present is all)organisms that don’t move that much( worms, echinoderms, plankton, bacteria) budding: tapeworms; fragmentation: earthworms: Annalids
  • Advantage: genetic variation; set of genes from each parent: weeds out weaknesses or harmful mutationsDisadvantage: need to find a mateBetter: animals that are on the move; places where there are abundant number of individuals in a population

    1. 1. Marine Science Review
    2. 2. Scientific method• What are the steps that we address in our lab notebooks?1.2.3.4.5.6.7.
    3. 3. • What happens to the amount of energy as you go up the pyramid?
    4. 4. Food Webs• What do the arrow mean?• What are the producers?• Primary consumers?• Secondary consumers?• Tertiary consumers?
    5. 5. Try this one!: producer, each level of consumers are?????
    6. 6. Now put into a food pyramid
    7. 7. Keystone species food web- what iskeystone species? How do you know?
    8. 8. Invasive species: can you tell what the invasive species are?
    9. 9. Can you think of adaptations that animals we discussed have had?• Cephalopods: what is an example of a cephalopod? – Modified mantle to swim in open water – Beak from radula to crush prey – Males modified organ to deposit sperm so females don’t eat them• Fish: – body shapes adapted for habitat – Coloration for mates, defense or camouflage
    10. 10. Questions so far???????• Continue to work on vocab…• We will continue to review on Friday (when your vocab is due!!!!)
    11. 11. Day 2 Review: Osmosis and Diffusion• What is osmosis and diffusion?• Hypertonic solution?• Isotonic solution?• Hypotonic solution?• What happens to an animal cell when placed in these solutions?
    12. 12. Plate Tectonics• What are the type of boundaries and ecosystems related to each? – Convergent (subduction) • What ecosystems do you find here? • What adaptations for animals? – Divergent • What newly discovered ecosystems here • What adaptations for animals? – Hot Spots • What ecosystems are formed?
    13. 13. Reproduction• Asexual- What process is this type? • what is the advantage? • What is the disadvantage? • When would this be the better method of reproduction? • What types of organisms reproduce this way? • Types of a asexual: budding: offspring grows out of parent, fragmentation: part of parent breaks off that can reproduce
    14. 14. Reproduction• Sexual – what process is this type? • what is the advantage? • What is the disadvantage? • When would this be the better method of reproduction? • Types external and internal fertilization. – Which has higher survival rate? – What organisms reproduce these ways?
    15. 15. Taxonomy• How do you classify species into groups?• How can you find the scientific name of a species unknown to you?
    16. 16. Population Density• What data do you collect in the field?• What organisms are best to sample this way?• What can this data tell you about other organisms living in this ecosystem?
    17. 17. How are organisms affected by these in an ecosystem• Abiotic Factors • Biotic Factors• Temp • Other organisms• Salinity • Plants• Turbidity • animals• Pressure• Amount of sunlight• Pollutants• Weather conditions
    18. 18. Properties of Water• Polar molecule• Cohesion• Adhesion• Viscosity• Density• Ability of light to penetrate**** how are animals affected by these?****what adaptations do they have?
    19. 19. Exam Topics• Food webs and trophic levels• Keystone/invasive species• Osmosis and diffusion• Taxonomy• Properties of water• Population sampling• Scientific method• Phylums we have discussed this year• Reproduction• Plate Tectonics
