Final answer:
Salmon laying large numbers of eggs is an example of high fecundity or r-strategy in reproduction. This increases the chances of survival for some of the offspring. Other fish species use spawning to increase fertilization and embryo survival.
Step-by-step explanation:
Salmon laying large numbers of eggs is an example of high fecundity or r-strategy in reproduction. This strategy involves producing a large number of offspring with minimal parental care, increasing the chances of survival for at least some of the offspring. Other examples of high fecundity are found in fish species that engage in spawning, where a large group of adults release their gametes into the water simultaneously to increase the chances of fertilization and the survival of some embryos.
