All the creatures breathe to live. Breathe-in oxygen. Breathe-out carbon dioxide. The creatures use certain mechanisms to breathe. For example, the Man use their lungs, the fishes use Gills, and the gapeworm from its scarfskin. Sometimes, the frogs breathe by their scarfskin too. In spite of having lungs. However, the breathe way is unusual for the insects. 

How do the insects breathe? www.teach-brain.com

A look at the insect’s belly, a number of opens or pores, is seen. An elephant needs to breathe 100 times in one minute. A mouse needs to breathe-in and out 200 times in one minute. 

The oxygen that insects breathe needs the oxidation of its nutrition elements. The corpse needs that to purge wastes, including water and carbon dioxide partially.
