The Food Chain

The sun produces energy through a thermonuclear reaction. The energy is transferred across space in the form of light and heat. 

When the energy reaches Earth, it is taken in by plants, in chemical form (carbon dioxide and water), through the process of photosynthesis. 

The chemical energy is taken in by the cow when it eats the plant. When the cow becomes a food product, the chemical energy is transferred to the food.
