Type I survivorship curve
Type 1 = high survivorship when young, and low at old age
Type I
type III
A type 2 survivorship curve implies a roughly constant mortality rate across all age groups of the species.
Type II
type 1 is what it seems like but its type 2
Chimpanzees are Type I organisms, and have cucarachas in thier pants.
Seagulls and other birds
a Type III curve -The greatest mortality is experienced early on in life, with relatively low rates of death for those surviving this bottleneck. This type of curve is characteristic of species that produce a large number of offspring
elephants
Type I: Type I survivorship curves are characterized by high survival in early and middle life, followed a rapid decline in survivorship in later life.Type II: Type II curves are an intermediate between Type I and III, where roughly constant mortality rate is experienced regardless of age.Type III: In Type III curves, the greatest mortality is experienced early on in life, with relatively low rates of death for those surviving this bottleneck.
