Why is fishes Breathing rate is more than terrestrial beings ?
Give a Brief point...
Answers
Answer:
The breathing rate of aquatic animals is more as compare to the breathing rate of terrestial organisms because, organisms living on the land inhale the oxygen which is present in abundance in our environment so they need not to breathe fast to take oxygen present in the atmosphere as the amount of oxygen is enough for terrestrial beings. But aquatic animals breathe faster because the amount of dissolved oxygen in water is very less than the amount of oxygen present in the atmosphere. So, in order to take sufficient oxygen they need to breathe faster than terrestrial organisms.
Answer:
The amount of dissolved oxygen is fairly low compared to the amount of oxygen in the air, the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms. Fishes take in water through their mouths and force it past the gills where the dissolved oxygen is taken up by blood.
