Questions 1. Examine the survivorship curves for the soap bubble populations. How do they correlate
with the Type I, II, and Ill survivorship trends? Explain.
2. Do any of the bubble populations show constant death rate for at least part of their
lifespan? If so, which
3. How did the treatments that bubble populations 1, 2, and 3 were subjected to affect the
shape of their curves?
4. For Population 3, which had to cross the line in order to be counted, what did the “line”
represent for a population of living organisms?
5. Which type of survivorship curve describes a population of organisms that produces a
very large number of offspring, most of which die at a very early age, only a few surviving
to old age? Give an example of a population of this type.
6. What reproductive strategy (r or K) would you expect each population to have? Explain
each of these strategies.
7. Would you expect a population in which most members survive for a long time to
produce few or many offspring? Which would be most advantageous to the population
as a whole? Explain.
8. Suppose a human population exhibits a Type Ill survival curve. What would you expect to
happen to the curve over time if a dramatic improvement in medical technology takes
place? Explain.
