Answer:
By the process of respiration
Explanation:
Insects breathe through spiracles (small opening) all over their body.Though oxygen is vital to an insect but excess oxygen damage its tissue. The opening and closing of spiracles controlling this gaseous exchange.It exhales carbon dioxide as it requires without inhaling oxygen. Insects breathing is very efficient tubes of air branch throughout their body.By this system air and carbon dioxide transfer faster than blood as in humans.
Within the food chain energy can be passed from one organism to another.Food chain starts with producers they are eaten by primary consumers followed by secondary consumers.The same system also found in case of ladybug.
