density dependent factor-

Density dependent factors are things that affects a population more when there is a larger population.
disease is a density dependent factor because when there is a larger population it is easier to spread a disease around thus killing off more of the population.

more examples of density dependent factors are competition for resources such as food, water, territories, mates, and nesting sites.
another example is predation because when there is a larger population of one animal then there is a larger population of predators because the more that they can feed the more they can reproduce, and they can reproduce faster as well. so this can also drastically effect a population as well.
