Plants recombine the chemical elements in carbon dioxide (CO2 ) and water (H2O) to form different products in a process known as photosynthesis. During photosynthesis, plants make a sugar called glucose, which they use as food. Glucose (C6H12O6 ) is a compound that contains carbon along with hydrogen and oxygen. Plants use this food to build leaves and other structures in their bodies. In the carbon cycle, carbon can move from plants to animals. How do you think this happens
