Summary Introduction
Introduction: The survivorship curves are used to represent the total number of members of a cohort that are still alive at each age. These curves are based on a cohort of 1,000 individuals. Different life spans of the species on the same graph can be compared using a logarithmic scale on the y-axis and a relative scale on the x-axis.

- Which of the following would not be an example of density-deperident factors regulating population size? The number of possible territories for robins is limited; thus when population sizes are high, a lower proportion of individuals can produce offspring. A. O B. In conditions of overcrowding, some desert pupfish living in ponds will emigrate to other ponds if given the opportunity. C.Predation on mosquitofish is high, regardless of population size. D. In conditions of high density, mice are more susceptible to mortality from heat stress. E.
