The second law of thermodynamics states that some energy is lost as heat in every energy exchange. However, life on Earth continues because Earth is an open system and continually receives new energy from the sun. This incoming energy allows living organisms to maintain their organization and carry out metabolic processes. Therefore, choice C is the best answer. The other choices do not provide a sufficient explanation for how life can continue despite the second law of thermodynamics.
