Sharks obtain all of their energy by eating other marine organisms, such as fish. Suppose that a marine scientist measures the chemical energy found in a system consisting of a fish and a shark. After the shark consumes the fish, the marine scientist finds that the total energy in the system decreases. If true, would this result validate or invalidate the Law of Conservation of Energy? Why or why not?


Invalidate, because energy should not leave a closed system

Invalidate, because the amount of energy should stay constant

Validate, because this scenario describes an open system

Validate, because the overall energy in the ocean is still unchanged
