  1. How populations grow Section 5.1

  2. Characteristics of populations • Geographic distribution (range) • Population density • Growth rate • Age structure

  3. Geographic distribution

  4. Population density • Number of redwoods on the Olympic Penninsula

  5. Population density • Number of penguins in the Crozet Archipelago

  6. Growth rate

  7. Growth rate • Depends on: • Birth rates • Death rates • Immigration • Emigration

  8. Age structure • Graphical representation of gender and age groups in an area/country

  9. Exponential Occurs under ideal conditions Out of control growth Logistic Occurs as resources become less available Population growth slows/stops Eventually a carrying capacity is reached Growth patterns

  10. Carrying capacity • Number of eggs in a carton • Number of ounces in a gallon of milk • Students in a room • Now you come up with some examples!

  11. Complete Analyzing Data pg 123
