Therefore, we can understand that the energy we obtain from food is essentially light energy stored within the food we consume!

Natural sources include the sun and stars; living things that give off light, such as fireflies; and artificial sources, which are created by humans and include light bulbs. HOW DO WE SEE THINGS? When light from a source of light such as an electric bulb falls on a book, a part of it is bounced off. When this bounced light falls on our eyes, we can see the book. This bouncing off of light by objects is called reflection of light. Page 5 Light and Shadow WHAT IS LIGHT? We have studied photosynthesis, where green plants produce food using sunlight energy.
