Chapter 53, Problem 2IQ
Summary Introduction
To determine: The type of survivorship curves represented in the given graph.
Introduction: The survivorship curve represents the total number or the proportion of members of a cohort that are still alive at each age.
Summary Introduction
To determine: The characteristics of some typical species that are related to each curve.
Introduction: The survivorship curves are based on a beginning cohort of 1,000 individuals. It uses a log scale on the vertical y-axis and a relative scale on the x-axis, so that species with different life spans can be compared on the same graph.

Discuss the types of survivorship curves, explaining the life history features found in organisms possessing different types of curves. Give at least 1 example of each.
For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators.
Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.
Plot survivorship curves for all three species illustrated in Table 1 on a single graph. Label the axes and provide a clear legend
convert it and make use of legend, so for the first species it would be 6months=1unit, then for the second species 1yr=1unit, and the third species would be 50yrs=1unit
