Some factors that limit population size depend on the density of the population how many individuals occupy a certain amount of space Density dependent factors include limited food limited breeding space and predators Density independent factors do not depend on population density For example, an oil spill affects all the birds in the area regardless of their density Population ecology helps us understand human population growth and where we might be headed next
