Read the passage. Then explain why the circulatory system of a grasshopper does not need to carry gases to and from the grasshopper's cells.
Passage
The diagram shows part of a grasshopper's respiratory system. Air passes
into and out of openings in its sides. These openings are connected to tubes
and air sacs that fill with air. The air tubes branch into tiny tubes that spread
out and are found close to all cells. So, unlike other animals, the grasshopper
does not exchange gases using its circulatory system.
