Final answer:
Bryozoans send their sperm into the water to fertilize eggs released by females.
Step-by-step explanation:
Bryozoans, which are filter-feeding invertebrates found in freshwater and marine habitats, release their sperm into the water. The sperm is then carried by the water current to find and fertilize the eggs released by female bryozoans. This process allows for sexual reproduction and the production of offspring.
This method of sperm release and fertilization is common among many aquatic animals, including mollusks, fishes, and amphibians, which rely on water for reproduction.
Therefore, bryozoans send their sperm into the water to fertilize eggs released by females.
