R-Strategist K-Strategist Baird’s Tapir Brazil Nut Cecropia Oryzomys rice rat
K-Strategist Baird’s Tapir Brazil Nut Species that produce a few, often large offspring or seeds, but invest a great deal of time and energy to ensure that most of the offspring or seeds will reach reproductive age…. A K-strategist is characterized by: 1) large parental investment in the young or seeds. K-strategists reproduce slowly, with long gestation periods, to permit the young to develop more in the womb. After birth, the young are tended until they can be reasonably expected to care for themselves, and... 2) the ability to exploit stable environmental situations. Once the population of a K- strategist has reached the carrying capacity of its environment, the population size stays relatively constant.

To compensate, an r-strategist produces a large number of offspring or seeds, most of which will not survive long enough to reproduce, and... 2) the ability to rapidly exploit unpredictable environment opportunities. An example of this is the Cecropia.
