1. Populations Mr. Haase

2. What is a population? All members of a species living in the same place at the same time

3. Properties of Populations Density- number of individuals per unit area Dispersion- arrangement of individuals in given space

4. How do you measure population growth? Change in Population size = Births - Deaths

5. Reproductive Potential Maximum number of offspring each member of a population can produce

6. Exponential Growth

7. What limits overpopulation? Carrying capacity- maximum population an ecosystem can support

8. Factors that limit population growth Resource Limits Competition

9. Population Regulation Density Dependant When deaths occur more quickly in crowded populations Examples: Black Plague Pine Beetle Density Independent Deaths occur regardless of population density Examples: Severe Weather Natural Disasters
