7. Dispersion Notebook questions Pg.18  1. What is the most common type of dispersion?  a. List reasons why this pattern is most common.  b. Give 3 examples of this pattern in a real ecosystem  2. What is the likely dispersion pattern of fish that swim in schools, seabird nesting on a small field, and thistles growing in a fairly uniform field?  3. What affects the size of populations? Think broadly and what affects the human and non-human population?  4. What would be the likely cause of bushes of one species growing in one area in a uniform spaced pattern?  a. random distribution of seeds  b. interactions among individuals in the population  c. chance  d. equal nutrient supplies in that area  e. variation in sunlight  5. Define dispersion:

8.  Discover how patterns of survivorship relate to the classic three types of survivorship curves. 2/12 Objective

9.  Age diagrams show us the relative number of individuals at each age. Survivorship curves can show us characteristics of the population.  Key Point #1: Survivorship curves show us survival characteristics of the population. Survivorship curves

10. Describe the characteristics of these populations:

13. Compare and contrast these organisms to one another.

14.  Type I: High survival rate in young Effective parenting Overall low death rates  Type II: Constant death rate Limited parenting  Type III: High death rate in young No parenting A lot of offspring because so many die Once survive till a certain age, high survival rate Survivorship Curves

15. Match the curves to the populations Type IType 2Type 3

16. Let connect the dots
