Question

A model is a representation, substitute, or simplification of what is being studied, but it is also similar to what it represents. There are many types of models, such as physical, conceptual, or mathematical models. Models have both advantages and limitations. The model below represents the cycle of matter between photosynthesis and cellular respiration.


Which of the following is a limitation of the model shown above?

a. the model shows synthesis of new compounds
b. the model is insufficiently labeled
c. the model represents two different processes rather than one
d. the model contains too many arrows

Answer 1

Answer:

The correct option is b. the model is insufficiently labeled

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.
