Question

2. Explain how insects breathe?​

Answer 1

Oxygen and carbon dioxide gases are exchanged through a network of tubes called tracheae. Instead of nostrils, insects breathe through openings in the thorax and abdomen called spiracles. Insects that are diapausing or non-mobile have low metabolic rates and need to take in less oxygen

Explanation:

Insects breathe in and out through holes, called spiracles, all over their bodies. Some insects close the holes now and then. Scientists had thought maybe they stopped breathing to limit water loss or to adapt to environments loaded with carbon dioxide, but no solid evidence supported either idea.
