Animals that possess exoskeletons are limited in the maximum size they can reach. As an animal gets larger its shell must increase in size in order to support its weight. This causes the surface to volume ratio to decrease. As this ratio decreases, it becomes more difficult for the animal to obtain enough oxygen for cellular respiration and space for internal organs is also lost with a thickening shell.
Insects shed their exoskeleton in order to grow. They expand quickly before the next exoskeleton hardens.
Most insects have small holes in the exoskeleton that is called the trachea. Oxygen is delivered directly to the insects tissues via the trachea.
Insects do not have a backbone, they have an exoskeleton. Most insects have wings. Therefore insects have no backbone, but they do have wings.
No, cockroaches, like all insects, are invertebrates and have an exoskeleton.

The Exoskeleton
Insects do have exoskeleton! Exoskeleton is an external skeleton that supports and protects an animal's body so they do need it and they do have it but I am not sure if all insects have exoskeletons
Yes, like all insects bees have an exoskeleton.

most of them do

Yes, the exoskeleton and wings do help insects to be a successful species. The hard exoskeleton protects internal organs and while wings allow movement.
It is a true exoskeleton. It supports the internal organs of the insect. Insects have no endoskeleton within their bodies.
All insects present an exoskeleton, so all insects are arthropods.
Yes, like all insects.
some do and some dont.
