Lab: Graphing and Interpreting a Survivorship Curve BIOLOGY Background: A survivorship curve is a generalized diagram showing the number of surviving members over time from a measured set of births. By measuring the number of offspring born in a year and following those offspring through until death, survivorship curves give information about the life history of a species.

Procedure: 1. Graph Data: Plot the data in Data Table 1-3 showing the number of Survivors vs. Percentage of maximum life span in the graph below. Construct a line graph showing the three different types of survivorship curves (see pages 438-439). Use different colors for each of the three survivorship curves and include a key.

3. What type of organisms are represented by the three types of curves? Type 1Type 2Type 3-
4. Rank the three survivorship curves from lowest to highest birth rates.
5. Rank the three survivorship curves from lowest to highest death rates.
6. Which curve show an equal chance of dying regardless of age? 7. Do you think there is any relationship between survivorship curves and reproductive strategies? Explain
8. An organism has ten offspring. Two of these offspring die each year over a five-year period. Is the organism more likely to be a bird or an insect? Explain
9. Using the graph you constructed, estimate how many cockroaches would survive by the time they reached 50% of its maximum lifespan?
10. What percentage of humans born will reach age 40 (roughly 50% of maximum lifespan)?
