Answer 1

like fishes only two chamber in their hearts the blood is pumped to the gills forgetting oxygenated and from there it passes directly to rest of the body.

Answer 2

Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O2 as compared to water. Since the content of O2 in the air is high, the terrestrial animals do not have to breathe faster to get more oxygen.
