What is the difference between the reproductive system of earthworms and ascaris?

The reproductive system of earthworms is hermaphroditic, meaning each individual possesses both male and female reproductive organs, allowing them to exchange sperm during copulation. In contrast, Ascaris, a type of roundworm, has separate sexes (dioecious), with distinct male and female individuals that reproduce sexually. Earthworms typically engage in external fertilization after mating, while Ascaris involves internal fertilization, with females laying fertilized eggs that are expelled into the environment. Additionally, earthworms produce fewer eggs with parental care, whereas Ascaris produces a large number of eggs with no parental involvement.
