6. 5 Niche

7. 6 Species that occupy similar niches but live in different geographical regions

8. 7 Ecological Equivalents

9. 8 What term refers to the concept that two species can not occupy the exact same niche?

10. 9 Competitive Exclusion

11. 10 What are the three possible outcomes of competitive exclusion?

12. 11 –One species is better suited to the niche and the other will either be pushed out or become extinct. –The niche will be divided. –The two species will further diverge.

13. 12 ___________ occurs when two organisms fight for the same limited resource

19. What is the difference between Interspecific and Intraspecific Competition? 18

20. 19 Interspecific – competition between separate species Intraspecific – competition between members of the same species

21. What are the two classes of parasites? Provide an example of each type. 20

22. 21 Endoparasites – (hookworms & tapeworms) Ectoparasites - leeches

24. 23

25. 24 What is the difference between population density and population dispersion?

26. 25 Density – number of individuals in a defined space Dispersion – how those individuals are spread out in that defined space
