predation, availability of food, disease, parasitism
Things that depend on the size of the population, as opposed to density independent factors such as weather, and natural disasters.
Density-dependent factors are factors that limit population growth such as, a natural disaster, disease, drought, fire, etc.May I add, food supply also falls under the density-dependent factor that involves population growth. When this happens, population does not level off but usually plunges down. In the factor of disease, an example would be the Great Black Plegue in England. It wiped out many people in just weeks.

Space and food sources are density-dependent factors.
The dependent variable is what the results yielded. For example, if you are testing humans, the dependent variable will be the test subject's answers. Some people also say it is what you are testing for if it is not testing on humans. For example, "the differences in growths of bacteria".
in dependent variable
A density dependent factor is a factor that is affected by the amount of organisms in a population. An example of this would be sickness, as the higher the density is, the more easily the sickness will spread.
Space and food sources are density-dependent factors.

Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.

Limiting factors whose effects increase as the size of the population increases are known as density-dependent factors. Competition is an example of a density-dependent limiting factor.
A density-dependent factor is one where the effect of the factor on the size of the population depends upon the original density or size of the population. A disease is a good example of a density-dependent factor. If a population is dense and the individuals live close together, then each individual will have a higher probability of catching the disease than if the individuals had been living farther apart. Not only will a greater number of individuals be affected, but, more importantly, a greater proportion of the population will be affected if they are living close together. For example, bird populations are often regulated more by this type of regulation.
