Final answer:
All organisms that make their own food are classified as autotrophs. Autotrophs use photosynthesis to produce energy-rich organic molecules.
Step-by-step explanation:
All organisms that make their own food are classified as autotrophs. Autotrophs are able to produce their own energy-rich organic molecules through processes like photosynthesis. They use sunlight and carbon dioxide to produce glucose, which provides them with the energy they need to survive and grow. Examples of autotrophs include plants, algae, and some bacteria.
