Answer:
C.
Step-by-step explanation:
By doing this he is demonstrating that organisms decay and carbon atoms return to the soil. Just like in the carbon cycle parker is taking apart the toy car (the car represents organism decay) in order to obtain its building blocks which the car was made out of (which represents carbon atoms). Once the building blocks are obtained he will reuse them to make something different, which is what carbon atoms do when they return to the soil.
