  • Carbon Cycle

    The process of photosynthesis involves the absorption of CO 2 by plants to produce carbohydrates. The equation is as follows: CO 2 + H 2 O + energy (CH 2 O) n +O 2. Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration.
