Answer:
Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.
Explanation:
Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.
As a mollusc, the animal probably has a mantle and a radula.
Molluscs are aquatic species that belong to the phylum of Mollusca. Mollusca is one of the biggest and most diverse phyla of the sea.
A mantle is a term that describes the fold in their body which secretes the hard protective shell of their body. A radula is a toothed structure (similar to the tongue) used to collect food.
