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.
