Earth's Cycles: Water, Rock, and Carbon

How are cellular respiration and photosynthesis related?

• They are the same reaction, which means that their reactants (starting substances) and their products (ending substances) are exactly the same

• They are opposite reactions, which means the products (ending substances) of photosynthesis become the reactants (starting substances) of cellular respiration and vice versa

• Photosynthesis and cellular respiration are not related

• They are both processes of breathing but one is for plants and one is for animals
