Question

The rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms. Give reason. State the pathway of air from nostrils to lungs in human beings.

Answer 1

the rate of breathing in aquatic animals is faster than that seen in terrestrial animals because the amount of oxygen dissolved in the water id less as compared to the amount of oxygen present in the air . thus the try to absorb as much oxygen a they can and hence their breathing rate is faster to consume more oxygen at a time.

Answer 2

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.
