Unlike animals, plants themselves make the food they need through a process called photosynthesis. "Photo" means light. "Synthesis" means putting together. Photosynthesis means putting together using light.
The raw materials needed for the process are found in the environment. Water comes from the soil. Carbon dioxide is one of the gases in the atmosphere. Energy for putting together carbon dioxide and water comes from the sun.
