5. cellular respiration is balanced by photosynthesis; the two processes work together to maintain the cycling of carbon and oxygen among earth systems. what describes the roles of carbon dioxide and water in these two processes? carbon dioxide and water are the reactants of both processes. b. carbon dioxide and water are the products of both processes. a. c. carbon dioxide is a reactant of photosynthesis; water is a reactant of cellular respiration. d. carbon dioxide and water are the reactants of photosynthesis and the products of cellular respiration.

The correct option is D) Carbon dioxide and water are the reactants of photosynthesis and the products of cellular respiration.

Explanation:

Photosynthesis can be described as a process in which plants convert carbon dioxide and water into glucose and oxygen in the presence of sunlight. Hence, carbon dioxide and water are the reactants of photosynthesis.

Cellular respiration can be described as a process by which organisms produce carbon dioxide and water from sugar and oxygen. Energy in the form of ATP is released by this process. Hence, carbon dioxide and water are the products of cellular respiration.
