Which explanation best describes the arrows in the model above?

Question 2 options:

Arrows 1 and 4 represent photosynthesis and arrow 2 represents respiration because photosynthesis releases carbon dioxide into the atmosphere and respiration utilizes carbon dioxide from the atmosphere.

Arrow 1 represents respiration and arrows 2 and 4 represent photosynthesis because photosynthesis releases carbon dioxide into the atmosphere and respiration utilizes carbon dioxide from the atmosphere.

Arrow 1 represents photosynthesis and arrows 2 and 4 represent respiration because photosynthesis utilizes carbon dioxide in the atmosphere and respiration releases carbon dioxide back into the atmosphere.

Arrows 1 and 2 represent photosynthesis and arrow 4 represents respiration because photosynthesis utilizes carbon dioxide in the atmosphere and respiration releases carbon dioxide back into the atmosphere.
