WebLike animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean. There is also oxygen in the atmosphere which has accumulated over hundreds of millions of years. WebIn those cramped subterranean quarters, oxygen levels may plummet from the normal 21 percent to 6 percent, while the amount of carbon dioxide — the waste gas that air-breathing animals exhale — can reach 7 to 10 percent, far higher than in surface air. Without biological mechanisms to cope with low or no oxygen, naked mole rats would die.
