Question

In new world monkeys have mortality rates are fairly low over time until they reach old age when the mortality rate increases sharply. This is an example of which kind of survivorship curve?

Answer 1

Answer: Type I survivorship curve

Explanation: Survivorship and reproduction rates determines changes in population size especially in populations not experiencing immigration or emigration.

Survivorship curves are graphical representations of the proportion or numbers of a demographic population (cohort) alive at varying ages.

Survivorship Curve Type I describes mortality rates that are fairly low over time until they reach old age, when the mortality rate increases sharply. They are flat at the beginning, which is a reflection of low death rates during early and middle life. This then drops sharply as death rates increase among older age-groups. Population groups in the type I survivorship curve usually produce few offspring which are provided with good care and includes large mammals including humans.

Answer 2

Type 1 survivorship curve

Step-by-step explanation:

Type I survivorship curve can also be referred to as convex curve; this kind of curve is characterized by significantly low mortality (high survival rate) between early life and middle life but usually followed by high mortality rate (low survival rate) as the organism approaches old age or later in life. In other words, death usually occurs at old age. This type of survivorship curve is usually typical of human and other larger mammals including monkeys.
