Question

why is atmosphere called the place where exchange of games in nature occurs?​

Answer 1

Your meanf gases...

You know that during respiration of living beings and burning of materials, carbon dioxide is produced along with some other gases. ... All gases go into the atmosphere. Thus, it is a place in Nature for gaseous exchange.

Gas exchange occurs in microscopic dead-end air-filled sacs called alveoli, where a very thin membrane (called the blood-air barrier) separates the blood in the alveolar capillaries (in the walls of the alveoli) from the alveolar air in the sacs.
