Final answer:
Autotrophs produce food through the process of photosynthesis.
Step-by-step explanation:
Autotrophs produce food through the process of photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (food) and oxygen. During photosynthesis, autotrophs capture the energy from sunlight and use it to produce organic molecules that serve as the building blocks for food.
