11. TURN IN YOUR BELLRINGER!

12. May 18, 2009 AGENDA: 1 – Bellringer 2 – Powerpoint: Population Graphs 3 – Activity: Analyze the graph HOMEWORK 1.Finish graph analysis (1 Page Minimum)

13. Linear Graph Example

14. Exponential Growth

15. Exponential growth until the carrying capacity is reached

16. New Vocabulary Carrying Capacity Density-dependent factor Density-independent factor Exponential Growth Life-history pattern

17. Carrying Capacity:

18. Density Dependent vs Density Independent Factors Space Water Nutrients/food Shelter Competition Predation Disease Parasitism Natural Disaster Temperature Sunlight Human Activities Physical characteristics Behaviors

19. Rapid Life History Patterns Most organisms which fit this category live in changeable or unpredictable environments. They have a small body size, mature rapidly, reproduce early & have a short life span. When the environment changes rapidly, most of the population dies & the survivors who hold the desirable trait go on to reproduce. Example: bacteria

20. Slow Life-History Pattern Usually large species that live in more stable environments. Example: bears, elephants, etc…

21. Activity Description (write this down!): Analyze graph (look at ALL details) Write 1 page describing 1.Pattern of graph (linear, J-curve or S- curve), organism(s) described, who would find this useful? 2.Separate the factors listed into either density dependent or density independent factors. 3.Summarize the graph in one paragraph.
