Question

how can photosynthesis be related to cellular respiration? they both have the same reactants (need the same things) they both produce the same products these 2 processes have nothing in common whats produced by one is needed for the other

Explanation:

Photosynthesis produces glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. The products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and the products of cellular respiration (carbon dioxide and water) are the reactants for photosynthesis.

Answer:

What's produced by one is needed for the other.
