Detailed explanation-2: -anoxic (an-OX-ick) A condition in which the aquatic (water) environment does not contain dissolved oxygen (DO), which is called an oxygen deficient condition. Generally refers to an environment in which chemically bound oxygen, such as in nitrate, is present.

Detailed explanation-3: -Hypoxia (environmental), an environment with low, or near-zero, oxygen content, commonly called anoxia; Anaerobic (disambiguation), a technical word which literally means without air (where “air” is generally used to mean oxygen), as opposed to aerobic; Aerobic (disambiguation), antonym of anaerobic.

Detailed explanation-4: -Anoxic anoxia happens when there’s not enough oxygen available to your body. If there isn’t enough oxygen to breathe in, you won’t be able to get enough oxygen to your bloodstream. One form of anoxic anoxia can happen when you’re at high altitudes.
