Question

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?
a. Carbon dioxide and water are the reactants of both processes.
b. Carbon dioxide and water are the products of both processes.
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.

Answer 1

d. Carbon dioxide and water are the reactants of photosynthesis and the

products of cellular respiration.

Step-by-step explanation:

Photosynthesis turns CO2 and water into oxygen and glucose. Plant foods are glucose and oxygen is a by-product. glucose.

Cellular breathing turns oxygen and glucose into carbon dioxide and water.

Water and carbon dioxide are byproducts, while ATP is

process-transformed energy.
