Question

The rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms. Why?​

Answer 1

The rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms because aquatic organisms do not take oxygen directly because oxygen is dissolve form in water while terrestrial organisms take oxygen directly from atmosphere.

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 .
