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.
Bacteria and other parasites are density dependent.
For example, tuberculosis which is caused by a bacteria that is spread through the air when someone who is infected sneezes or coughs, and it infects a higher percentage of people in high-density cities than in rural areas.
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.
Mass and volume are density dependent factors
food supply
Space and food sources are density-dependent factors.
density dependent
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.
When the population of similar animals increase in habitats the amount of recources become limited
The factors that distort the way the independent variable affects the dependent variable are referred to as the double-blinds. The factors try to explore the relationship between the dependent and independent variables.
Food, water, and natural resources are the most common examples of density-dependent factors.
Two examples of density independent factors of the tundra biome are the extreme temperatures and the excessive winds. Two examples of density dependent factors are weather and competition between the species.
Space and food sources are density-dependent factors.
Density dependent factors are factors that depend of the population (density). Such as food, water, and space Density Independent factors are factors that the population (density) depends on. Such as weather, natural disasters and random occurances.

A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.
Density dependent limiting factors are factors that limit/change population when they reach a certain population level/density. For example: if there are too many fish in a pond, food might run out, and fish may end up dying. Some other examples are disease, food shortage, predation, competition, and lack of living space (crowding).
The density dependent factor refers to the factors that affect the size or growth of a given population density. The factors also affect the mortality rate and the Birth Rate of a population. Some of the density dependent factors are disease, parasitism, availability of food and migration.
