Final answer:

Terrestrial spiders use either book lungs or a tracheal system to perform respiration and breathe air.

Step-by-step explanation:

Terrestrial spiders, such as land spiders, use different respiratory structures to breathe air. They have either book lungs or a tracheal system. Book lungs are found in arachnids like spiders, scorpions, ticks, and mites. Book lungs consist of a stack of tissue layers resembling the pages of a book, allowing for efficient gas exchange. On the other hand, a tracheal system is common in insects and myriapods. It consists of a network of tubes called tracheae that branch throughout the body, ending in tiny tracheoles where gas exchange occurs.
