Relationships Among Marine Organisms

Marine Food Web:    When completing the food web activity it became quit clear that the Bull Shark is on the top of the food chain. The Bull Shark is at the top of the food chain because they do not have any other species that can harm or kill it other than humanity and illnesses. Bull sharks are known to be able to devour anything but it mostly concentrates on injured or weakened fish. Since the bull shark is a shark it would be badly hurt if the food in which it mainly ate, somehow became extinct or disappeared forever. If the main food source had died out, the top species would slowly dissipate because it wouldn't have food to survive on. But the species that had been feed on by the now new extinct fish species (that the Bull Shark survived on) would overpopulate because there is no crowd control.Now if the Species the Bull Shark feeds on went extinct the bull shark species would dramatically decrease or maby even become extinct itself if it cannot find new food sources. But then there would be an overpopulated sea of plankton and other small organisms because there are no fish and sharks can't survive on those tiny things.

I was not in class for the food web activity.
