Detailed explanation-1: -r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments. 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-2: -r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K).

Detailed explanation-3: -The life history theory behind r-selected species assumes that by having a larger number of offspring, there is a higher chance that at least some will survive to adulthood. Alternatively, K-selected species spend a lot of time and energy rearing only a few offspring.

Detailed explanation-4: -R-selected species are generally small, fast-growing organisms that live in unstable environments and produce a large number of offspring, while K-selected species are typically large, slow-growing organisms that live in stable environments and produce only a few offspring that they can give a lot of care to.

Detailed explanation-5: -R-and K-selection constrain the range of viable species through the colonization-competition tradeoff, with strong r-selection favoring colonizers and strong K-selection favoring competitors, but the level of disturbance also affects the success of species.
