Final answer:
A species with a survivorship curve showing a constant chance of dying at any age would exhibit a Type II survivorship curve, characteristic of many bird populations.
Step-by-step explanation:
If a species displays a survivorship curve where the chance of survival is independent of age, they would exhibit a Type II survivorship curve. This curve represents a scenario where the mortality rate is relatively constant throughout the species' lifespan, meaning that it is equally likely for an individual to die at any age. Bird populations often display this intermediate Type II curve. In contrast, a Type I survivorship curve is characterized by low mortality in early and middle life with higher mortality in older age, which is typical of humans and many large mammals. On the other hand, a Type III survivorship curve is associated with high mortality in the early stages of life, with individuals that survive past these stages having a better chance of continuing survival. This pattern is often seen in species like trees and marine invertebrates that produce large numbers of offspring with little parental care.
