In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Matter can change forms, but only one kind of energy exists. B. Energy can change forms, but only one kind of matter exists. C. Matter and energy can change forms and locations in ecosystems. D. Matter and energy must always remain in the same form and location.
