The original source of energy in your food is?

The original source of energy in our food comes from the sun. Plants capture the sun's energy through the process of photosynthesis. During photosynthesis, plants use chlorophyll, a green pigment, to convert light energy into chemical energy. This chemical energy is stored in the form of glucose, a simple sugar. When we eat plants, we consume this stored energy. Animals, in turn, obtain energy by eating plants or other animals that have eaten plants. Therefore, the sun is the ultimate source of energy for all life on Earth.
