WebSome are density-dependent, while others are density-independent. Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. One example is competition for limited food among members of a population. WebIn words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance.
