Logistic Growth and Carrying Capacity
Captions available
The idea
Logistic growth occurs when growth slows as population size nears carrying capacity, the maximum size an environment's resources sustain, producing an S-shaped curve that levels off.
In practice
A population introduced into a new habitat grows quickly, then levels off near carrying capacity as resources tighten.
Where people slip
Carrying capacity is set by resource limits, not any fixed number the species determines independent of habitat.
