Forklaring
S-shaped growth curve(sigmoid growth curve) A pattern of growth in which, in a new environment, the population density of an organism increases slowly initially, in a positive acceleration phase; then increases rapidly, approaching an exponential growth rate but then declines in a negative acceleration phase until at zero growth rate the population stabilizes.
