Anoxia means there is no oxygen. Anoxic is used in biology to refer to habitats with little or no oxygen. A related term is hypoxia, which means low oxygen.

Anaerobic usually means the same thing: an anaerobic organism is one which does not need oxygen.

Anoxic events occur when an area of ocean loses most of its oxygen below the surface layers.
