Populations of organisms that have sigmoid growth curves
limited by the carrying capacity are called K-selected.
Species are divided into two selected species, R-selected
species and K-selected species. K-selected
species are <span>also called K-strategist. These are the species whose populations vary at or near the <span>carrying capacity <span>(K) of the </span></span>environment<span> in which they live.</span></span>
