Why do the number of organisms in a group change from the first step to the last step of a dichotomous key? A
The number of organisms decreases because the number of common characteristics of the organisms in a group increases.
B
The number of organisms increases because the number of common characteristics of the organisms in a group increases.
C
The number of organisms is cut in half because the number of common characteristics of the organisms in a group decreases by half in the last step.
D
The number of organisms stays the same because the number of common characteristics of the organisms in a group decreases by half in the last step.
