Question

what advantage over an aquatic organism does a terreatrial organism have with regard to obtaining oxygen for respiration?

Answer 1

Hey... I think this can be ur answer!!

Aquatic organisms have to take up dissolved O2 which is small in amount in water than in atmosphere...

SO the rate of breathing in aquatic organisms is more than other organisms who obtain O2 from air.....

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.
