  1. HONORS BIOLOGY Chapter 13 and 14 Quiz 1. Define the following terms: (1 each) -competitive exclusion- the result of competition in which one of the species is locally extinct from the community -niche- the role of an organism in the habitat. -keystone species- important species that has a large effect on the ecosystem -herbivore

  2. Explain two interspecific interactions that may occur in a community. (4)- predation, competition, symbiosis

  3. 6. Explain how two squirrels both feeding on the nuts of an oak tree avoid the consequences of competition. (3)-the squirrels might exploit a different portion of the habitat. 7. What effect does competition have on a community. (2)

  4. Figure 53-05 What is the prey defense seen here?- Camouflage

  5. Figure 53-06 What is the prey defense seen here? Aposematic Coloration

  6. Identify the type of mimicry evident in the next two slides Slide 1 Batesian Slide 2 Mullerian

  7. LE 53-7 Green parrot snake Hawkmoth larva

  8. LE 53-8 Cuckoo bee Yellow jacket

  9. Identify the type of distribution in the next three slides. • Explain the interactions that maintain the distribution pattern seen

  10. LE 52-3b Uniform- organisms are territorial and defend their territory

  11. LE 52-3c Random- environment typically has an abundance of resources. Usually seen in plants that randomly disperse their seeds.

  12. LE 52-3a Clumped- Organisms are highly social and work in groups for better opportunities to feed and for survival

  13. 1,000 I LE 52-5 100 II Number of survivors (log scale) 10 III 1 100 50 0 Percentage of maximum life span

  14. View the previous slide to answer the following • Which type of survivorship curve indicates a high parental investment on the young? How? Type I • Which curve shows a constant rate of death? How? Type II

  15. What type of growth curve is A? B? 2,000 A. Exponential 1,500 LE 52-12 K = 1,500 B. Logistic Population size (N) 1,000 500 0 0 15 10 5 Number of generations

  16. What is the difference between the two curves in the previous slide. What is the carrying capacity of the population? What does this mean? 1500, the environment can sustain this number or individuals without a decline in the population
