Q: When energy is captured or transformed, it inevitably degrades and becomes what less useful form of energy?


Read this paragraph and choose the correct option from the provided answers:

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.

 Choices:

- chemical

- temperature

- motion

- heat


A:
heat
