Question

2. As you have learned about arthropod and mollusc, how does the
exoskeleton differ in both.

Accepted Answer

Unlike mollusk shells, the exoskeleton of arthropods does not
grow along with the rest of the animal.

The mollusk exoskeleton, or shell, also contains high levels of
calcium carbonate minerals, making it more rigid compared to that of
the arthropods.
