Question

What can one infer from a relatively linear survivorship curve and what organism generally exhibits?

Answer 1

Answer:

The missing options are:

A. the mortality rate is roughly uniform across the lifespan of this organism; birds

B. the mortality rate is higher for older members of this population; humans

C. the mortality rate is higher for younger members of this population; oak trees.

The correct answer is A.

Explanation:

There are three types of survivorship curves:

• Convex type: in this type of curve, there is a high rate of survivorship, they have long lives and die old.

• Concave type: shows low survivorship rate after birth, these organisms have short lives.

• Lineal type: the lineal type is between the two previous types. It shows a constant survivorship rate and mortality rate throughout the lifetime of the organism. This type of curve is normal in birds and mice.
