A Type I Survivorship Curve is ___________

Question

A Type I survivorship curve is ___________  
A) convex, such as that of humans
B) diagonal, such as that of lizards, small mammals, and large birds
C) concave, such as marine animals that release eggs
D) S-shaped, such as that of small birds
E) logarithmic, such as that of weeds

Accepted Answer

A Type I survivorship curve is convex, which means that the rate of mortality is low in the early and middle stages of life, but increases rapidly in later life. This is characteristic of many large mammals, including humans, who tend to have a relatively high rate of survival through childhood and early adult life, but face increasing mortality as they age.
