Which of the following best describes the difference between a Type I and a Type III survivorship curve?
A
Type I curves are only found in plants, while Type III curves are only found in mammals.
B
Type I curves represent species with constant mortality rates throughout life, while Type III curves represent species with low mortality in early life and high mortality in old age.
C
Type I curves show high survival rates in early and middle life, with most mortality occurring in old age, while Type III curves show high mortality early in life with few individuals surviving to adulthood.
D
Type I curves are typical of organisms that produce many offspring with little parental care, while Type III curves are typical of organisms that produce few offspring with extensive parental care.
Verified step by step guidance1
Understand the concept of survivorship curves: Survivorship curves are graphical representations that show the number of individuals surviving at each age for a given species. They help illustrate patterns of mortality and survival within populations.
Learn about Type I survivorship curves: Type I curves are characterized by high survival rates during early and middle life, with most mortality occurring in old age. These curves are typical of species that invest heavily in parental care and produce fewer offspring, such as humans and large mammals.
Learn about Type III survivorship curves: Type III curves show high mortality rates early in life, with only a few individuals surviving to adulthood. These curves are typical of species that produce many offspring with little or no parental care, such as fish, amphibians, and plants.
Compare the two types: The key difference is that Type I curves represent species with high survival in early and middle life and mortality concentrated in old age, while Type III curves represent species with high mortality early in life and survival concentrated in adulthood.
Apply this understanding to the options provided: Evaluate each statement based on the definitions of Type I and Type III survivorship curves. The correct answer is the one that accurately describes the survival patterns and reproductive strategies associated with these curves.
