AP BIOLOGY

Detailed explanation-1: -Organisms exhibiting a type I survivorship typically produce few offspring and provide good care to the offspring increasing the likelihood of their survival. Humans and most mammals exhibit a type I survivorship curve.

Detailed explanation-2: -Why is long-term parental care not associated with having many offspring during a reproductive episode? Parental care is not feasible for organisms having many offspring because they do not have the energy available to take care of offspring.

Detailed explanation-3: -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-4: -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.
