Which process releases energy in a fish’s body?

• Breaking food down using carbon dioxide

• Reacting oxygen with food molecules during cellular respiration

• Physical mixing of food with stomach acids

• Combining water and nutrients in the bloodstream

During cellular respiration, the carbon atoms in the food are:

• They are rearranged to form carbon dioxide.

• They are destroyed during the digestion process.

• They stay in the fish's body permanently.

• They become part of water molecules.

• Its food contains chemicals that break down muscle.

• Its food is hard to digest and provides little energy.

• It spends most of its time in cold temperatures.
