they have short life spans relative to other organism

few young are produced at one time
|
|
|
they reach carrying capacity
|
Detailed explanation-1: -K-selected species possess relatively stable populations fluctuating near the carrying capacity of the environment. These species are characterized by having only a few offspring but investing high amounts of parental care. Elephants, humans, and bison are all k-selected species.
Detailed explanation-2: -K-Selected Traits These organisms tend to reach sexual maturity late in life. Once reproductively active, K-selected species typically only have a few offspring in a single breeding event, though may reproduce many times throughout their life.
Detailed explanation-3: -The predicted characteristics of these K-selected individuals are therefore larger size, deferred reproduction, iteroparity (i.e. more extended reproduction), a lower reproductive allocation and larger (and thus fewer) offspring.
Detailed explanation-4: -Humans are the most K of all. K’s supposedly have a longer gestation period, a higher birthweight, a more delayed sexual maturation, a lower sex drive, and a longer life.
