A population in which most of the organisms survive well past the midpoint and die near the very end of the life span have a _____ survivorship curve.
A population in which most of the organisms survive well past the midpoint and die near the very end of the life span have a _____ survivorship curve.
The correct option is A A
Ecologists use survivorship curves to visualize the survival strategies of different organisms. Examples of populations with Type I survivorship include humans in developed countries and animals in zoos. A lot of effort is invested in each individual, resulting in high survivorship throughout the life cycle. Most individuals die of old age.
In Type II survivorship, the mortality of an individual does not depend on its age. Commonly listed examples of this include rodents, adult birds, and certain turtle
species.
Most individuals in populations with Type III survivorship produce many thousands of offspring, most of whom die right away. Once this initial period is over, survivorship is relatively constant. Examples of this include fishes, seeds, and marine larvae.
