The second law of thermodynamics states that when energy is converted from one form to another, the amount of useful energy decreases. how does this relate to energy flow through biological systems? choices are:if you don’t 100% sure don’t answer it animals need to absorb solar energy (heat) to metabolize biological molecules for the energy they contain. as energy is passed from producer to consumer, some energy is lost as heat a biological system cannot create or destroy energy. as producers, plants must liberate heat as they synthesize carbohydrates
