Question

why is the rate of breathing in aquatic organisms much faster then in terrestrial organisms

Answer 1

Answer:

The breathing rate of aquatic animals is faster than that of terrestrial animals because the amount of dissolved oxygen in the water in much less than the amount on land, so they have to breathe more in order to get more oxygen

Answer 2

Aquatic organisms use oxygen dissolved in surrounding water . Since air dissolved in water has fairly low concentration of oxygen , the aquatic organisms have much faster rate of breathing .

Terrestrial organisms take oxygen from

the oxygen-rich atmosphere through

respiratory organs . Hence , they have

much less breathing rate than aquatic

organisms .
