Please answer the following question: Answer the following question given this paragraph: Physics also tells us that, although energy can be captured or transformed, it inevitably degrades, becoming heat, a less useful form of energy. This is why organisms require a constant input of energy; the work they must do uses up the energy they take in. Energy, unlike materials, cannot be recycled. The story of life is a story of energy flow its capture, transformation, use for work, and loss as heat. Q: When energy is captured or transformed, it inevitably degrades and becomes what less useful form of energy? Choices: - chemical - temperature - motion - heat A:
A:
heat
