AP Biology: Chapter 53-Community Ecology 1. Give the definition and an example (if appropriate) for the following terms: a. Community b. Interspecific interaction c. Interspecific competition d. Competitive exclusion e. Ecological niche f. Resource partitioning g. Character displacement 2. Describe Gausse’s experiment with Paramecia. 3. Fill in the chart of interspecific interactions: Interaction Effects on population density Example Predation Herbivory Parasitism Disease Mutualism Commensalism 4. Describe several defense mechanisms to predation in plants. 5. Define and give an example of the following animal defenses: a. Cryptic coloration b. Aposematic coloration c. Batesian mimicry d. Mullerian mimicry 6. What is meant by the “trophic structure” of a community? 7. What does a food web show that isn’t indicated by a food chain? 8. What limits the length of a food chain? 9. Define a dominant species, invasive species, and keystone species. 10. Explain why keystone species are so important to a community. 11. Define ecological succession. 12. What is the difference between primary and secondary succession? 13. Explain how each of the following biogeographic areas affect community biodiversity: a. Equatorial-Polar Gradients b. Area Effects c. Island Equilibrium Model
