If a population does not have any restrictions, it can continually grow, BUT in real life, there are limitations such as food or predator relationships that prevent a population from growing exponentially.
THIS IS KNOWN AS THE J CURVE
Slide14What Can Limit Growth?
Limiting factors are factors that limit the growth of the population. Ex: Availability of food, Disease, Predators, Lack of space, etc.
These factors cause a S-Shaped growth curve.
