Final answer:
Higher light levels increase plant growth and food production by opening stomata, increasing photosynthesis.
Step-by-step explanation:
Higher light levels increase plant growth and food production by opening stomata, which allows for increased photosynthesis. Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into glucose, their food source. When stomata open, carbon dioxide enters the plant and is used in photosynthesis, leading to increased plant growth and food production.
