If you can take this energy and turn it into food what are they called?

If you can take energy and turn it into food, the process is typically referred to as photosynthesis in plants. During photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose and oxygen. The glucose serves as food for the plant and can also be consumed by other organisms in the food chain. In a broader sense, organisms that produce their own food using energy from sunlight or inorganic sources are called autotrophs.
