Which of the following is one way in which organisms such as clown fish and sea turtles are able to overcome the many dangers that their offspring encounter and ensure that their species population numbers stay relatively steady

I would say that animals such as sea turtles and clown fish protect there offspring by putting them in areas that are much harder for predators to access. Clown fish for example lay their eggs in the tentacles around a sea anemone to prevent predators from eating them because they are poisonous to all dish but clown fish. And sea turtles burry there eggs on land so that the predators cannot eat their eggs. Hope this helps.
