Answer 1

D Sharks keep populations of other fish healthy.

Step-by-step explanation:

They play a crucial role in maintaining the balance of ocean ecosystems. As top predators, sharks help regulate the populations of other fish species by keeping them in check. This prevents any one species from dominating the ecosystem and allows for a diverse and healthy marine environment. So, sharks are indeed important for the overall health and stability of ocean ecosystems.
