Compare and contrast Type I and Type III survivorship curves. Sketch a correctly labeled graph to
support your comparison. BONUS: Identify two organisms that represent each of the two types of
survivorship strategies discussed here. What will be an ideal response?
The sketch should resemble Fig. 53-8 on textbook p.1163. Both curves deal with the point in the life
cycle when most mortality occurs. In a Type I curve (exemplified by bisons and humans), the
probability of surviving is high early in life. In a Type III curve (exemplified by herring gulls early in
life and also oysters), the probability of surviving is high later in life.
