During the process of photosynthesis, plants convert carbon dioxide and water into glucose. Covalent bonds hold the glucose molecules together. The breaking of the covalent bonds during digestion releases energy.
Answer:
chemical energy
Explanation:
Photosynthetic organisms are autotrophs, or organisms that can make energy from inorganic compounds. Autotrophs are also called "producers." All non-autotrophic organisms, including humans, are heterotrophs, and rely on organic sources of chemical energy.
