Chapter 37 Communities & Ecosystems Due Wed. 5/9/09 1. Outline- Chapter 37 not typed, written in ink. 2. Vocabulary- on a separate sheet of paper number terms and write definitions. When there are 2 words (vs.) be sure to distinguish differences between them. Indent on the line below and write an example or sentence or draw a picture of the vocabulary. 1. community 2. interspecific 3. mutualism vs. parasitism 4. commensalisms vs. predation 5. ecological niche 6. resource partitioning * 7. competitive exclusion principle* 8. Batsian vs. Mueller mimicry * 9. antibiotic resistance 10. detrivore vs. decomposer 11. keystone species 12. primary vs. secondary succession 13. invasive species 14. biological control 15. chemical vs biogeochemical cycles 16. primary production 17. organic matter vs. abiotic reservoir 18. biomagnification* 19. eutrophication 20. denitrifying vs. nitrifying vs. nitrogen fixation * Found in lecture notes not in text 3. Review questions- number each one and answer on a separate sheet of paper. You do not need to rewrite the questions. 1. Describe the characteristics of a community & how interspecific interactions affect the dynamics of populations (p 742) 2. Explain 5 different aspects of ecological niche of hippos (p743 & p741) 3. Explain the types of adaptations that arose through evolution of prey species and plants (p744) 4. Describe the trophic structure of a community (p746) 5. Explain how species diversity is measured and how keystone species effect diversity (p748-9) 6. Describe the role of environmental disturbance on primary & secondary ecological succession (p750) 7. Detail the effect of one invasive species on a community (p751 or766) 8. Explain how energy supply is limited by the length of food chains (p753) 9. Why is meat considered a luxury for humans? (p754) 10. How do changes in chemicals affect ecosystems and how do altered ecosystems upset chemical cycling? (p758-9)
