notebooks?

3. • What happens
to the amount
of energy as you
go up the
pyramid?

4. Food Webs
• What do the
arrow mean?
• What are the
producers?
• Primary
consumers?
• Secondary
consumers?
• Tertiary
consumers?

5. Try this one!: producer, each level of
consumers are?????

6. Now put into a food pyramid

7. Keystone species food web- what is
keystone species? How do you know?

8. Invasive species: can you tell what the
invasive species are?

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. Questions so far???????
• Continue to work on vocab…
• We will continue to review on Friday (when
your vocab is due!!!!)

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?

13. 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?

14. 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

15. 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?

16. Taxonomy
• How do you classify species into groups?
• How can you find the scientific name of a
species unknown to you?

17. 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?

18. 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

19. 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?

20. Exam Topics
