The flow of energy from one form of life to the next begins with plants. Through the process of photosynthesis, plants harness the Sun's energy and use it to transform carbon dioxide and water into the food molecules that sustain them. The energy stored in these molecules nourishes not only the plants that produce them, but also nearly every organism on Earth. |
