DENDROLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Similarly, competition for food and other resources rises with density and affects an increasing proportion of the population. However, as density decreases, such as through mortality or migration, the influence of density-dependent factors also decreases.

Detailed explanation-3: -Density-independent limiting factor: The factors that can affect the population’s per capita growth rate that is independent of how dense the population is called density-independent limiting factors. Natural disasters, pollution, and weather are some examples of a density-independent limiting factors.
