Quizplus · Accepted Answer

The second law of thermodynamics states that in any energy transformation or transfer, some energy is lost as heat. Therefore, living systems also emit heat as they undergo energy transformations, making option C the correct observation. Option A is incorrect, as living systems often utilize high-quality energy sources such as glucose through cellular respiration. Option B is incorrect, as cooking food does not change its energy quality but rather makes it more digestible. Option D is not directly related to the second law of thermodynamics and is an inaccurate statement.
