1. Population Growth Biology Ch 5-1& 5-2

2. Exponential Growth  Under ideal conditions with unlimited resources and protection from predators/disease, a population will grow continually  The larger it gets, the faster it grows

3. Logistic Growth  Population’s growth slows and then stops following a period of exponential growth  Eventually populations run out of space and resources

4. Carrying Capacity  The maximum number of individuals the environment can support  Once carrying capacity is reached, factors act to stabilize it at that size

5. Population Limitations  Density Dependent Factors  Limitations of a population due to the size of the population  Density Independent Factors  Affect all populations in similar ways, regardless of population size and density

6. Limiting Factors

7. Density Dependent  Predation/Parasitism  Resource Competition  Food, water, shelter  Health  Disease

8. Explain the graph!

9. Density Independent  Natural Disasters  Tornado, Hurricane, Volcanism, Human activities etc.
