Question

what happens to the air a dolphin breathes as it moves and grows?

Explanation:

When a dolphin breathes, it inhales oxygen-rich air into its lungs. As it moves and grows, the dolphin uses cellular respiration to break down food, consuming oxygen from the inhaled air and producing carbon dioxide. The carbon dioxide is then exhaled back into the air. The oxygen supports metabolic processes for growth (like building new cells and tissues) and energy for movement.

Answer:

As the dolphin breathes, moves, and grows: it takes in oxygen from air, uses the oxygen in cellular respiration to generate energy for movement and fuel growth (building new body tissues), and then exhales waste carbon dioxide back into the air.
