5. All food chains start with ENERGY from the sun

6. carbon dioxide from the air energy from sunlight (or light) water from the roots food transported to the rest of the plant

7. carbon dioxide from the air energy from sunlight (or light) water from the roots food transported to the rest of the plant Photosynthesis
