Answer 1

Answer:

It happens in different specialized organs in different oragnisms.

Explanation:

In higher organisms, like mammals, birds, reptiles and amphibians, the alveoli of the lungs is where the exchange takes place.

In animals, like earthworm, frogs and so on, the moist skin of the organism helps in exchange of gases.(cutaneous breathing)

In insects, presence of spiracles and trachea helps in exchange of gases.

In crustaceans and some fishes, gills are present for exchange of gases.

In scorpion, crab, etc., an organ called book lungs does this function.
