Final answer:
R strategy refers to a reproductive strategy in biology where organisms have a high reproductive rate and produce many offspring with little parental care. Examples include most insects, small rodents, and many marine organisms.
Step-by-step explanation:
R strategy refers to a reproductive strategy in biology. It is a term used to describe the life history traits and reproductive behavior of organisms. In biology, organisms can be classified into two main reproductive strategies: K strategy and R strategy.
Organisms following the R strategy tend to have a high reproductive rate, producing many offspring with little parental care. These offspring have a shorter lifespan and reach sexual maturity at an earlier age. Examples of organisms following the R strategy include most insects, small rodents, and many marine organisms.
On the other hand, organisms following the K strategy have a low reproductive rate but invest more in each offspring, providing them with more parental care. These offspring have a longer lifespan and reach sexual maturity at a later age. Examples of organisms following the K strategy include elephants, whales, and humans.
