K-selected species typically exhibit which type of survivorship curve?

• A. Type I
• B. Type IV
• C. Type III
• D. Type II

Answer: (A)

Verified step by step guidance

1. Understand the concept of survivorship curves: Survivorship curves are graphical representations that show the number of individuals of a species that survive at each age. There are three main types: Type I, Type II, and Type III.
2. Learn about K-selected species: K-selected species are characterized by traits such as long lifespan, late reproduction, and high parental care. They tend to invest more resources in fewer offspring.
3. Identify the characteristics of Type I survivorship curve: Type I curve is typical for species that have high survival rates in early and middle life, followed by a rapid decline in survival in later life. This is often seen in species with high parental care.
4. Compare the characteristics of K-selected species with the survivorship curves: K-selected species, due to their high parental investment and long lifespan, align with the Type I survivorship curve, where most individuals survive to old age.
5. Conclude the relationship: Based on the characteristics of K-selected species and the description of Type I survivorship curve, it is evident that K-selected species typically exhibit a Type I survivorship curve.
