- Density-Independent factors
- Density-Independent factors- Any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population
- Density-Dependent factors
- Density- Dependent factor- Any factor limiting the size of a population whose effect is dependent on the number of individuals in the population
- Growth Curves
- Exponential Growth- Population Grows at a constant rate
- Logistic Growth- Population Growth Slows or Stops completely
- Carrying capacity- Largest number of individuals of a population that a environment can support
- For populations which grow exponentially, growth starts out slowly, enters a rapid growth phase and then levels off when the carrying capacity for that species has been reached.
