Question
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.

- Describe the three types of survivorship curves and relate them to specific populationsarrow_forwardFor 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.arrow_forwardPlot survivorship curve of this barnacle population and indicate what type of survivorship curve it is.arrow_forward
