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.1155. 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.
