Final answer:
Species that are r-strategists are usually smaller than those that are K-strategists.
Step-by-step explanation:
False. Species that are r-strategists are usually smaller than those that are K-strategists. K-selected species are adapted to stable and predictable environments, and they tend to have larger, but fewer, offspring and contribute large amounts of resources to each offspring. An example of a K-selected species is elephants. On the other hand, r-selected species are adapted to unstable and unpredictable environments, and they have large numbers of small offspring. Examples of r-selected species are jellyfish and dandelions.
