All organisms need food as a source of molecules that provide chemical energy and building materials.

Plants make their own food in the form of sugar molecules from carbon dioxide molecules and water molecules. In the process of making sugar molecules, oxygen molecules are produced as well.

Plants use sugar molecules to make a variety of larger carbon-containing molecules that become part of their body structures.

Animals use carbon-containing molecules from food to make a variety of other carbon-containing molecules that become part of their body structures.

All organisms, including plants and animals, have mechanisms for storing molecules from food for later use.
