When a dolphin jumps, it moves its muscles and chemical potential energy is converted to kinetic energy. some of this energy is lost to the dolphin. explain why this phenomenon does not violate the law of conservation of energy. the dolphin is a closed system, so energy is allowed to exit the system. the energy is transferred to waves in the surrounding water. the muscles recapture the energy when they relax after contractions. the law of conservation of energy does not apply to biological systems.
