ANIMALS
? Compare and contrast the major animal phyla and classes discussed in class.
? You should know the information in the animal study guide charts that were e-mailed this
week. link
? Some questions will ask you to identify the phylum/class of animal base don its features, some
questions will ask you to determine which two animals are most closely related.
? Be able to explain the major transitions in the evolution of animals.
? Compare the transition from an aquatic lifestyle to a terrestrial lifestyle in animals with the
same transition in pla nts.

Are all exotic species invasive?
Discuss how San diego gets its fresh water.
Discuss the three major threats to San Diego’s fresh water supply.
Discuss potential solutions to the problem.
Do exotic species become invasive due to their features, the features of the habitat they invade? Explain.
Explain: exotic, alien, nonnative, introduced vs. native, endemic; naturalized
For what reasons do humans have such a large (and increasing) impact on the environment?
Give 2 examples of biological invasions and their impacts.
Give an example of how each element of "HIPPO" causes species extinctions and or environmental damage.
Give an example of how habitat loss, habitat fragmentation, overpopulation and overcconsumption cause species
extinctions and or environmental damage.
Has commercial fishing in the oceans increased, decreased, or stayed the same sinceWW2?
Has there been significant deforestation in the US?
