Marine Science Review
Scientific method
• What are the steps that we address in our lab notebooks?
1. 2. 3. 4. 5. 6. 7.
• What happens to the amount of energy as you go up the pyramid?
Food Webs• What do the
arrow mean?• What are the
producers?• Primary
consumers?• Secondary
consumers?• Tertiary
consumers?
Try this one!: producer, each level of consumers are?????
Now put into a food pyramid
Keystone species food web- what is keystone species? How do you know?
Invasive species: can you tell what the invasive species are?
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
Questions so far???????
• Continue to work on vocab…• We will continue to review on Friday (when
your vocab is due!!!!)
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?
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?
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
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?
Taxonomy
• How do you classify species into groups?• How can you find the scientific name of a
species unknown to you?
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?
How are organisms affected by these in an ecosystem
• Abiotic Factors• Temp• Salinity• Turbidity• Pressure• Amount of sunlight• Pollutants • Weather conditions
• Biotic Factors• Other organisms• Plants• animals
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?
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
