Answer:
Photosynthesis
Step-by-step explanation:
Green plants make their own food to facilitate its growth by converting the radiant energy from the sun into chemical energy through a process called photosynthesis. During the process, plants use carbon dioxide, minerals, water and energy from the atmosphere and emit oxygen during the day (when there's sun). A substance called chlorophyll found in green plants traps the energy from the sunlight to make food.
