Answer 2

Dear user!

❤️❤️❤️❤️❤️

● The rate of breathing is comparatively low in aquatic animals than terrestrial animals because the amount of water is much less.

● And the amount of oxygen dissolved on land is much more than water.

● As oxygen in the atmosphere is about 20.3% , than in water.

● So, they have to breathe more in order to get more oxygen.

Thanks ❤️
