Question

1. use the diagram below – label the three different survivorship curves – give an example of an animal that fits the curve and an explanation of why they fit the curve. page 1 of 4

Explanation:

There are three types of survivorship curves. Type - I: High survival of young and middle - aged individuals, with a high mortality rate in old age. Humans are an example as they receive parental care and have access to medical care in their early and middle years, but mortality increases with old age. Type - II: Constant mortality rate throughout life. Songbirds are an example as they face consistent risks from predation, disease, and environmental factors throughout their lives. Type - III: High mortality in the early stages of life, with low mortality once they reach adulthood. Sea turtles are an example as many eggs and hatchlings are eaten by predators, but adult sea turtles have fewer natural predators. Without the actual diagram, we can't label it, but these are the general explanations for the curves and examples.

Answer:

Type - I: Humans, high survival early and middle - life, high mortality in old age due to parental care and medical access early on and increased vulnerability with age.
Type - II: Songbirds, constant mortality rate due to consistent risks throughout life.
Type - III: Sea turtles, high early - life mortality from predation on eggs and hatchlings, low adult mortality as they have fewer predators.
