which statement correctly describes the diagram? a the products of photosynthesis cannot be used by other…

Brief Explanations:

Photosynthesis in plants, algae and some bacteria produces oxygen and sugars. Respiration in most living organisms uses oxygen and sugars to produce water and carbon - dioxide. The carbon - dioxide produced by respiration can be used by plants for photosynthesis. Option A is incorrect as the products of photosynthesis (oxygen and sugars) are used by other organisms. Option C and D are incorrect as the exchange of oxygen and carbon - dioxide occurs in both photosynthesis and respiration.

Answer:

B. The products of respiration can be used by plants for photosynthesis.
