Answer 1

Answer:

Gas exchange is important because it provides oxygen to the cells of living organisms so that they can obtain energy from organic molecules.

Explanation:

Rhythmic contractions of abdominal muscles compress air sacs increasing ventilation which helps to maintain a concentration gradient during vigorous activity such as flying. This increases the rate of gas exchange when the insect is more active and has an increased metabolic demand (needs more oxygen).
