During photosynthesis, the following reaction takes place:

Question

carbon dioxide + water + light energy → sugar + oxygen

During cellular respiration, the following reaction takes place:

sugar + oxygen → carbon dioxide + water + chemical energy

Given this information, how are photosynthesis and cellular respiration related?
A.
Photosynthesis and cellular respiration both start with the same materials.
B.
Photosynthesis and cellular respiration both produce the same materials.
C.
The same type of energy is found in both photosynthesis and cellular respiration.
D.
The products of photosynthesis are the reactants of cellular respiration.

Answer 1

The correct answer is:

D. The products of photosynthesis are the reactants of cellular respiration.

In photosynthesis, the products are sugar and oxygen, which serve as the reactants for cellular respiration. This connection highlights the cyclical relationship between the two processes in the ecosystem.
