Information about a species' death rate at different ages can be summarized by a survivorship curve. The horizontal axis represents different ages in the life of an individual of that species. The vertical axis indicates the number of offspring that survive a specific age to make it to the next age. Taken together, the curve shows how many individuals of different ages remain alive over time. Age The adjacent survivorship curve represents a curve for an unknown species. Which of the following statements correctly describes the characteristics of a species that might produce this curve? This species has few offspring at a time and thus is able to put a lot of effort into raising them. The offspring have a high survival rate, and the highest death rates are in older adults. This species has a steady rate of survival versus death. Offspring are not more likely or less likely to die than adults are. In other words, roughly the same number of individuals die at every age in the species. This species has many offspring at a time and does not put in much, if any, parental effort. Many of the offspring die early, and few survive to older ages. Number of survivors (logarithmic scale)

The adjacent survivorship curve represents a
curve for an unknown species. Which of the following statements correctly describes the
characteristics of a species that might produce this curve?
This species has few offspring at a time and thus is able to put a lot of effort into raising them. The offspring have
a high survival rate, and the highest death rates are in older adults.
This species has a steady rate of survival versus death. Offspring are not more likely or less likely to die than
adults are. In other words, roughly the same number of individuals die at every age in the species.
This species has many offspring at a time and does not put in much, if any, parental effort. Many of the offspring
die early, and few survive to older ages.
