Final answer:
Semelparous animals produce many offspring with a low chance of survival to adulthood, characterizing a strategy of a single, resource-intensive reproductive event.
Step-by-step explanation:
Semelparous animals produce many offspring, and the offspring have a low chance of surviving to adulthood. Semelparity is a life history strategy characterized by a single reproductive event followed by the death of the organism. Species that exhibit semelparity allocate most of their resources to reproduction at once.
This strategy is often observed in species that produce a large number of offspring with minimal parental care, such as many marine invertebrates and some types of fish. The mass production of offspring is a bet-hedging strategy to ensure that at least some will survive to adulthood despite the lack of parental investment.Semelparous animals produce many offspring with a low chance of survival to adulthood, characterizing a strategy of a single, resource-intensive reproductive event.
