You are presented with the question "What plant processes convert carbon dioxide, water and solar energy into carbohydrates?" and the following answer choices: 
- water types
 - life-sustaining
 - chlorofluorocarbons
 - food tools
 - planting pots
 - circulatory systems
 - one celled organisms
 - peachleaf willow

Now knowing that photosynthesis means producers convert from carbon dioxide, water, and solar energy into carbohydrates for themselves and photosynthesis and cellular respiration are life-sustaining plant processes, choose the best answer.
