Answer:
<em>The correct option is b. the model is insufficiently labeled</em>
Explanation:
Models showing certain cycles should clearly show the reactants and the products being formed. They should be able to depict the various changes in the reactants which lead to the formation of the products.
The diagram shown in the picture is a poor depiction for the process of photosynthesis as well as cellular respiration. I does not tell us the products being formed. Like oxygen gas is released during photosynthesis but it is just labelled as gas in the diagram. The sugar being formed is also not named which is glucose.
