Question

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

Answer 1

Aquatic animals get oxygen in dissolved form whereas terrestrial organisms get oxygen directly from atmosphere. Thus the rate of breathing in aquatic animals is fast than the terrestrial ones.

Hope it helps buddy

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.
