Where do sharks fit in the food chain?

Sharks are top predators in the food chain, meaning they are at the highest level and have no natural predators. They feed on a wide range of prey, including fish, seals, sea lions, turtles, and even other sharks. Some of the largest shark species, such as the great white shark and the whale shark, can even prey on marine mammals such as dolphins and whales. Sharks play an important role in maintaining the balance of the marine ecosystem by controlling the populations of their prey species.
