Final answer:
The reproductive strategy where few young are produced at repeated intervals throughout an individual's life is known as iteroparity, which is common in K-selected species that provide substantial parental care to ensure higher juvenile survival.
Step-by-step explanation:
The reproductive strategy in which relatively few young are produced at repeated intervals during an individual's life is called iteroparity. This stands in contrast to semelparity, where an organism reproduces only once and then typically dies. Iteroparity is characterized by multiple reproductive events, often with less offspring at each event that may receive more parental care and have higher survival rates due to their parents' investment. An example of iteroparity is the reproductive behavior of K-selected species, which tend to have fewer offspring but provide greater parental care, resulting in a higher survival rate of the juveniles. Precocial and altricial strategies also fit into this framework; altricial species need lots of care before they can survive on their own, while precocial species are more autonomous early on.
