Question

Quizplus · Accepted Answer

Type I survivorship curves are characterized by low mortality rates early in life (i.e., a high probability of survival), but high mortality rates later in life. Organisms that exhibit this pattern tend to have low reproductive rates (i.e., low r) and produce relatively few large offspring that require extensive parental care to ensure their survival. Examples of species with type I survivorship curves include humans, elephants, and whales.
