WebApr 8, 2024 · Views today: 5.75k. In ecology, a density independent factor, also known as a limiting factor, is any force that influences the size of a population of living things regardless of population density (number of individuals per unit area). Often, the density-independent factors arise from the chemical and physical (rather than density biology ...
WebNegative density-dependence, or density-dependent restriction, describes a situation in which population growth is curtailed by crowding, predators and competition. [citation needed] In cell biology, it describes the reduction in cell division. When a cell population reaches a certain density, the amount of required growth factors and nutrients ...

Webdensity-dependent factor: any factor that regulates the size of a population under natural circumstances by acting more severely on a population when it is large than when it is small. Thus as numbers increase so does competition for resources, e.g. food or nesting material. Such factors can affect either the birth rate or the mortality, but ... WebDefinition of density-dependent limiting factor. Population growth limiting factors are divided into two categories: density-dependent and density-independent. The first type of limiting factor that we will be exploring is density-dependent limiting factors. Density-dependent factors include competition, predation, resource depletion, and diseases.
WebJun 8, 2024 · Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions such as fire.
