Question

What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration

Answer 1

a terrestrial organism has an advantage over aquatic organisms because it can breathe easily compared to aquatic organisms because the % of oxygen is high in air than water. 

Answer 2

♤The amount of oxygen dissolved in water is fairly low as compared to the amount of oxygen present in air.

♤ the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms.

♤ Fishes take in water through there mouth and force it past the gills where the dissolved oxygen is taken up by the blood.
