AP®︎ Environmental Science: Topic 3.5 Flashcards

The total amount or rate of supply of resources capable of supporting a population

The portion of the resource base that members of a population can actually access and use

An environmental condition or scarce resource that restricts population growth; another abundant resource cannot compensate for it

An individual’s or population’s reproductive output or capacity to produce offspring

The incidence of death in a population

A relationship in which a limiting factor’s effect becomes stronger as population density increases

Competition among members of the same species for limited resources

Competition between different species that use the same limited resource

The potential per-capita rate of population increase under favorable conditions, reflecting reproduction minus mortality

Growth by approximately the same proportion per interval, producing increasing absolute additions and a J-shaped curve; Nₜ = N₀(1 + r)ᵗ.

S-shaped growth that slows as limiting factors intensify and the population approaches carrying capacity

The maximum population size an environment can sustain over time under its current conditions and resource base

The combined effect of limiting factors that prevent a population from reaching its unrestricted growth potential

A temporary increase of a population above its carrying capacity

A delay between a resource change and the resulting change in population size, mortality, or reproduction

A substantial population decline following overshoot or a major reduction in resource availability
