Final answer:
Primates are examples of K-strategists, which are adapted to stable environments, have larger, but fewer, offspring, and provide parental care. R-strategists, on the other hand, are adapted to unpredictable environments and have large numbers of small offspring.
Step-by-step explanation:
Primates are examples of K-strategists in terms of life-history strategies. K-selected species are adapted to stable, predictable environments. They tend to have larger, but fewer, offspring and provide a significant amount of resources and parental care to each offspring. Examples of K-selected species include elephants, while marine invertebrates like jellyfish are examples of R-strategists, which are adapted to unstable and unpredictable environments and have large numbers of small offspring.
