Detailed explanation-1: -r-Selected Species Such species reproduce often and produce large numbers of offspring. It is this ability to have a high intrinsic growth rate that allows r-selected species to rapidly surpass their carrying capacity.
Detailed explanation-2: -Although not always the case, r-selection is more common among smaller animals with shorter lifespans and, frequently, non-overlapping generations, such as fish or insects.
Detailed explanation-3: -R-selected species have many offspring per reproductive age. However, r-selected species have a Type III survivorship curve, which means a shorter lifespan and that most offspring die off at an early age.
Detailed explanation-4: -K-Selected Species Examples In the animal world, most large mammals are also K-selected.
