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.

carbon

explanation:

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
