It depends on their new food source, but it could have drastic affects. The fish populations would start growing because they wouldn't have a predator depleting their numbers, and all of their food sources would drastically decrease because there would be higher numbers of fish eating them. Also, whatever the sharks started eating would vastly decrease, and whatever was usually eating that food source would now have to compete with the sharks. Unless their food source is nothing, in which case they will starve.
If sharks had legs, they would not be sharks.
The whole world is done, sharks are extremely important, they keep EVERYTHING in balance. The ocean life would reproduce and ther would be large amounts of everything. Well sharks are very important to the underwater ecosystem, and without them the fish and other shark prey would over populate and which would affect the rest of the food chain.
No, both species are filter feeders. Eating small schooling fish, shrimp, krill, and plankton. They most definitely would not eat each other.
They will die.
Sharks and other predators help by culling out the weak and sick animals so that the population is healthier than it would be, and they keep the prey animals from overpopulating and eating all the food in the area, which would cause starvation.
Because you might run into a man eating sharks. +++ I'd have thought the prospect of a man eating sharks would only be frightening if you are a shark - and algebra would not help you in that situation!
he would probaly die
the producers would decrease in population as the herbivores which the sharks would have ate, would grow in population.
For a Given value of 'friendly' Yes, it might not be very interested in frolicking merrily through the ocean with you, but it would be quite incapable of eating you, and they are very docile.
the whole way of life underwater would change because the lesser species would slowly become larger and larger in population and eventually kill other species by eating all of the resources available.
You would be eating waaaay to much for that to happen.
They get their energy by eating. Bull Sharks are apex predators. They are known to eat any living creature that lives in its surroundings. Its diet would include fish, turtles, dolphins, crustaceans, other smaller bull sharks etc. They are also known to attack humans. They usually chase and attack their prey.
