Oxygen exchange through the skin makes the greatest contribution to c) amphibians. Air is taken in through the nasal passage or the mouth, it then crosses the palate to the trachea, where the glottis divides the air to both bronchi, from where gas is transported to the lungs. Gills vary in structure from animal to animal. So they breathe faster, but there is abundant O… 1. Since the amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air, the rate of breathing in aquatic organisms is much faster due to the low concentration of oxygen in the aquatic environment than that seen in terrestrial organisms. Reptiles breathe through the lungs. However, terrestrial animals strive to overcome this problem of water loss by adopting the following methods which can be referred to osmoregulatory adaptations .

The fat is metabolized and releases fat, but this requires lots of oxygen to metabolize it (to liberate the water, they would need to breathe using more water than they would gain from metabolizing that fat) Frogs have the ability to breathe many different ways, due to their unusual life cycle and aquatic and terrestrial environment. Examining a cross-section through the middle of the animal's body under a microscope, Pirow saw steep oxygen gradients in haemoglobin-poor Daphnia but fairly flat oxygen gradients in haemoglobin-rich animals.
