Students are using a computer simulation to study the carbon cycle. The simulation allows students to manipulate only temperature in a region. The simulation focuses on the processes of photosynthesis and cellular respiration.

Question

Which statement describes a limitation of the model compared to the actual process?

(1 point)
Responses

The model allows for the manipulation of multiple variables to replicate their natural effects.
The model allows for the manipulation of multiple variables to replicate their natural effects.

The model simplifies the processes of photosynthesis and cellular respiration, by focusing on a single variable which does not happen in natural settings.

The model includes changes in carbon levels as they happen.
The model includes changes in carbon levels as they happen.

The model represents possible impacts on photosynthesis and cellular respiration without modifications.

Answer 1

The statement that best describes a limitation of the model compared to the actual process is:

The model simplifies the processes of photosynthesis and cellular respiration, by focusing on a single variable which does not happen in natural settings.

This statement highlights that the model is limited because it only considers temperature changes and does not account for the multitude of other factors that influence photosynthesis and cellular respiration in a natural environment, such as light, water availability, and nutrient levels.
