Which of the following traits is characteristic of K-selected populations?

• A. Have short lifespans and high juvenile mortality
• B. Reproduce only once before dying (semelparity)
• C. Exhibit rapid population growth and early maturity
• D. Produce few offspring with high parental care

Answer: (D)

Verified step by step guidance

1. Understand the concept of K-selected populations: K-selected species are those that thrive in stable environments and are characterized by traits that maximize survival and reproductive success in competitive conditions. They often invest heavily in fewer offspring, ensuring their survival through high parental care.
2. Compare the traits listed in the problem to the characteristics of K-selected populations: Traits such as short lifespans, high juvenile mortality, semelparity (reproducing only once), and rapid population growth are typically associated with r-selected populations, which prioritize quantity over quality of offspring.
3. Focus on the trait 'Produce few offspring with high parental care': This aligns with the K-selected strategy, as these species invest significant resources into raising fewer offspring to ensure their survival and success in competitive environments.
4. Eliminate the incorrect options: Traits like short lifespans, high juvenile mortality, semelparity, and rapid population growth are inconsistent with K-selected populations. These traits are more characteristic of r-selected populations.
5. Conclude that the correct answer is 'Produce few offspring with high parental care,' as this is the defining characteristic of K-selected populations, emphasizing quality and survival of offspring over quantity.
