• A population multiplies by a constant factor at constant time intervals.
That is the Exponential Growth of a population.

  • The environment can only be a host to a certain number of organisms.
The number of organisms in a population that the environment can maintain or "carry"
with no net increase or decrease is the Carrying Capacity.
Environmental factors limit a population's growth rate.

  • Limiting factors limit a populations growth.
They are conditions that can restrict a population's growth.
Ex: Food & space

  • Density-Dependent Factors are factors that limit a population more as population density increases.

  • Density-Independent Factors are factors that limit populations but are unrelated to population density.
Ex: Extreme weather.
