Which statement best describes the total number of carbon atoms during cellular respiration in the fish?
a. the total number of carbon atoms decreases because the carbon-containing
molecules from the food are destroyed during digestion.

b. the total number of carbon atoms increases because the carbon-containing
molecules from the food are used to make smaller carbon dioxide molecules.

c. the total number of carbon atoms stays the same because the carbon from
the carbon-containing food molecules is used to make molecules such as
carbon dioxide.

d. the total number of carbon atoms decreases because the carbon from the
