k-selected species

Detailed explanation-1: -K-selected species produce offspring that each have a higher probability of survival to maturity.
Detailed explanation-2: -R-selected species are influenced heavily by intrinsic growth rates ("r"), or the maximum population growth rate, and exhibit large increases followed by large decreases in population numbers. K-selected species are controlled more by carrying capacity ("K") and tend to display more stable populations.
Detailed explanation-3: -R-selected species are those that place an emphasis on a high growth rate, and, typically exploit less-crowded ecological niches. They produce many offspring, each of which has a relatively low probability of surviving to adulthood.
Detailed explanation-4: -In the equations describing growth of populations of organisms, r represents the slope of the line representing exponential growth. The letter K represents the carrying capacity of a habitat for members of a given sort of organism.
