Do all insects have exoskeletons? If not, how do they avoid getting hurt by other animals and plants while walking around outside?
Arthropods, which include insects, have exoskeletons, which are hard outer shells that protect their bodies. Exoskeletons are made of a tough, protein-based material called chitin. They provide insects with protection from predators, parasites, and environmental hazards. However, not all insects have exoskeletons. Some insects, such as grubs and maggots, have soft bodies that are not protected by an exoskeleton. These insects rely on other means to protect themselves from predators, such as camouflage or chemical defenses.
Insects that do not have exoskeletons are more vulnerable to predators and other threats. They may be more likely to be eaten by predators, or they may be injured by environmental factors such as UV radiation or extreme temperatures. However, these insects have evolved other ways to protect themselves, such as by living in protective environments or by producing chemical defenses.
