Solution

Breathing rate or respiratory rate:
Breathing rate is the number of times a person breathes in a minute.
A terrestrial organism can breathe slowly and can get its oxygen directly from the air.
Fish and other aquatic species obtain oxygen from the dissolved state of water.
There is less dissolved oxygen in water compared to the amount of oxygen in the air.
Creatures that live in water must breathe more quickly than animals that live on land in order to provide the body's cells with the oxygen they need to operate properly
