Se hela listan på study.com An r-selected species is one that has a large amount of offspring each year and does not devote much energy to raise said offspring. One example of a r-selected species that is found in a coral reef is coral itself. Coral is actually a colony of polyps which releases millions of young at a time in order to expand the reef.

These species grow very rapidly and attain reproductive maturity at early stage in their lives. R selected species have a large amount of offspring per reproductive age. However they have a Type 3 survival curve which means that most of the offspring die off during their early ages and the few live to their old age. 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.
