FACTORS AFFECTING POPULATION CHANGE Density
... When the predator’s population decreases the amount of prey will increase as there is less predators around to consume them. Disease can greatly affect the populations that are dense or overcrowded, since it is easier to be passed from one individual to another. Ex/ foot-and-mouth disease in cattle ...
