Photosynthesis

Photosynthesis is the process which plants make their own food from sunlight, carbon dioxide, and water.

H2O (water) + CO2 (carbon dioxide) + sunlight »»» C6H12O6 (glucose) + O2 (oxygen)

This can be likened to the statement "plants make their own food" as the plant produces its energy source (glucose) with water, carbon dioxide, and sunlight. The glucose made will eventually be used in the process of cellular respiration, in the mitochondria, where its energy will be converted into ATP.
