CATDOLL : CATDOLL: Locusts can fly in the air, and can also crawl or jump in dry land environments. The morphological structure characteristics that adapt to this are ( ) ① Breathing through trachea

Most arthropods are terrestrial animals. Since the climate on land is relatively dry, arthropods have a hard exoskeleton on their body surface, which is mainly used to protect and support the soft organs inside and prevent the evaporation of water in the body. This is one of the characteristics of adapting to life on land. The body of a locust is divided into three parts: head, thorax, and abdomen. The thorax has three pairs of legs and two pairs of wings, which expands the range of activities and helps locusts to find food, avoid enemies, and find mates. Locusts breathe through trachea and can adapt to the dry terrestrial environment. The presence of a pair of compound eyes on the head has nothing to do with the dry environment on land.
