Green plants (producers) can use light energy to make their own food
This process is called photosynthesis
Green plants are green because they contain a chemical called chlorophyll. This chemical is used to trap light energy.
Chlorophyll is contained in the chloroplasts of plant cells
Light energy is used to change carbon dioxide and water into starch and oxygen
The word equation for photosynthesis is
carbon + water starch + oxygen
