Final answer:
R-selected species, such as jellyfish and dandelions, have a large number of small offspring, while K-selected species, such as gorillas, elephants, and sharks, have a smaller number of offspring and provide long-term parental care.
Step-by-step explanation:
In biology, r-selected species are those that have a large number of small offspring, mature early, have short lifespans, and do not provide long-term parental care. Examples of r-selected species are jellyfish and dandelions.
Gorillas, elephants, and sharks are considered K-selected species. K-selected species generally have a smaller number of offspring, mature later, have longer lifespans, and provide long-term parental care. They are adapted to stable and predictable environments.
