Isabel needs an image to represent the carbon cycle for a presentation in her science class. She has the following diagrams to choose from (A.)model A would be the best model for the carbon cycle because carbon depletes over time as it is used by different organisms.
(B. )model B would be the best model for the carbon cycle because carbon will follow the same path when it is transferred from one place to another
(C. )model ac would be the best model for the carbon cycle because the carbon cycle has definite beginning and end where carbon eventually cannot be reused
(D. )model D would be the best model for the carbon cycle because the carbon cycle is a flow of matter which can take different paths bringing carbon back to the same place
