How do arthropods grow while being contained in an exoskeleton, which is a rigid, heavy structure?
1. Arthropods die when they grow too large for their exoskeleton.
2. Arthropods molt or shed their exoskeleton and replace it with a bigger one.
3. Arthropods leave their exoskeletons and find a larger, more suitable one left by another arthropod.
4. Arthropods grow no larger than the size of their exoskeleton.

Metamorphosis enables insects:
1. To be able to alternate between diploid and haploid generations.
2. To avoid expending the energy required to build an exoskeleton as a juvenile.
3. To hide from predators as juveniles.4. To lessen the competition for food sources between the
juveniles and the adults.
