Question

Photosynthesis and Cellular Respiration

The processes of photosynthesis and cellular respiration are interdependent—each process is necessary to fuel the other. The chemical products of photosynthesis are the chemical reactants of cellular respiration, and the products of cellular respiration are the reactants of photosynthesis.



During photosynthesis, plants, algae, and photosynthetic bacteria—together called producers—create their own food by capturing light energy from the Sun to make molecules of glucose. Organic molecules, including glucose, can then be stored as food to be broken down by cellular respiration when energy is needed.
All living organisms perform some kind of cellular respiration. During cellular respiration, chemical pathways containing organic molecules such as glucose are broken down to release energy in a quickly usable form. Essentially, cellular respiration is the opposite of photosynthesis.

The correct answer is **B. the blue arrows in a circle**.

This choice best illustrates the interdependent relationship between photosynthesis and cellular respiration, as it signifies the cycle where the products of one process serve as the reactants for the other, emphasizing how each process fuels the other.
