Carrying capacity definition, the maximum, equilibrium number of organisms of a particular species that can be supported indefinitely in a given environment. One way to address the challenges associated with making future projections is to look at current human impact on the planet. Carrying capacity, the average population density or population size of a species below which its numbers tend to increase and above which its numbers tend to decrease because of shortages of resources. Carrying capacity (K)is the average population density/size a habitat can accommodate for a particular species, above which its numbers tend to decrease due to a finite number of resources. d.
