Deep-ocean lantern fish have special organs that use chemical energy to produce light. However, the light can only travel a certain distance through the water before it is no longer visible. How does this phenomenon validate the Law of Conservation of Energy? The fish is a closed system, so energy is allowed to exit the system. The Law of Conservation of Energy applies to biological, not physical, systems. The light energy travels through the water until it is reflected or absorbed. The light is not carried by matter and contains no energy.
