D
Small body size
Verified step by step guidance1
Understand the concept of K-selected species: K-selected species are characterized by traits that are advantageous in stable environments where competition for resources is high. They tend to invest more in fewer offspring, ensuring higher survival rates.
Identify the typical traits of K-selected species: These species often have long lifespans, larger body sizes, and produce fewer offspring with higher parental care.
Analyze the options given: High reproductive rate and rapid maturation are traits more commonly associated with r-selected species, which thrive in unstable environments and produce many offspring with less parental care.
Recognize that a long lifespan is a typical adaptation of K-selected species, as it allows them to invest more time and resources into raising fewer offspring.
Conclude that the correct adaptation of a K-selected species from the options provided is a long lifespan, as it aligns with their strategy of maximizing offspring survival in competitive environments.
