which factor is density-dependent?
In the context of populations, a limiting factor is a factor that causes population growth to decrease. Density-Dependent Factors Density-Dependent Factors A limiting factor that depends on population size is called a density-dependent limiting factor. Density-Dependent Factors Density-dependent limiting factors include: â¢ competition â¢ predation â¢ parasitism â¢ disease Density-Dependent Factors Density-dependent factors operate only when the population density reaches a certain level. These factors operate most strongly when a population is large and dense. They do not affect small, scattered populations as greatly. Density-Dependent Factors Competition When populations become crowded, organisms compete for food, water space, sunlight and other essentials. Competition among members of the same species is a density-dependent limiting factor. Density ...
