Final exam studyguide summer 2010

  1. 1. Final Exam Studyguide Definitions: population ecology Population structure Population density life table Fecundity life history cohort demography Survivorship curves intrinsic rate of increase exponential growth model dN/dt = ri N carrying capacity Logistic growth model dN/dt = rN(K-N/K) r-selected K-selected J-Shaped curve S-Shaped curve Density dependent density independent clumped Random uniform managing populations Photosynthesis autotrophs primary producers Heterotrophs consumers trophic levels Primary consumers secondary consumers tertiary consumers Omnivores biomass Food chain food web detritivores parasitism Mutualism Commensalism amensalism Predator/prey competition prey adaptations cryptic coloration mechanical defenses warning displays Batesian mimicry mullerian mimicry interference competition exploitative competition interspecific intraspecific competitive exclusion community habitat trophic cascades ecosystem engineers keystone species disturbance succession (primary & secondary) intermediate disturbance species richness vs. species diversity physical environment oceans freshwater land atmosphere troposphere ozone upwelling zone groundwater stratosphere greenhouse gases solar energy gross primary production net primary production fossil fuels Biogeochemical cycles water cycle transpiration deforestation Carbon cycle nitrogen cycle phosphorous cycle Ecosystem sustainability conservation biology extinctions Threatened species endangered species species-area relationship Habitat destruction Introduction of exotic species Overexploitation Climate change invasive species Bleaching preserves centers of imminent extinction restoration ecology reconciliation ecology The Convention on International Trade in Endangered Species (CITES) Potential essays: 1. Explain the differences between the Exponential and Logistic growth models. Include the equations and diagram both curves. 2. Discuss the characteristics of r-selected and K-selected species. Draw the three survivorship curves. 3. List all of the different types of relationships organisms can have when they interact. Explain the relationships giving examples of each. A chart may help you get started. 4. Explain primary and secondary succession and give an example of both. 5. Complete a water cycle by drawing all players in a cycle. Explain how water runs through its complete cycle. What does the future hold for us if the water cycle is not modified?
  2. 2. 6. Explain conservation biology and the steps needed to make a change! 7. Explain the carbon cycle thoroughly a diagram will help identify the cycle then write the process. 8. Draw a food web and identify all of the players involved. Explain how much energy is lost as you go up the food chain. 9. List and explain the different warning displays organisms can produce. Why are they important? 10. What type of diversity do oceans, freshwater and terrestrial physical habitats play a role in? Give some examples of organisms that live in each area.
