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 .
