Final answer:
Photosynthesis converts the carbon in carbon dioxide into the carbon in sugar.
Step-by-step explanation:
Photosynthesis is a process in which plants and bacteria convert carbon dioxide, water, and light into glucose and oxygen. The correct statement that describes how photosynthesis is involved in the carbon cycle is: The carbon in carbon dioxide is converted into the carbon in sugar. During photosynthesis, carbon dioxide is taken in by plants and converted into glucose (sugar) through a series of chemical reactions. This glucose can then be used as a source of energy for the plant or stored for later use.
