Anaerobic means without air, or, more specifically, oxygen.

It can refer to conditions, to processes, or to organisms.

Anaerobic conditions are ones in which oxygen is excluded or has been used up.

Anaerobic processes (usually biological, but not necessarily) are chemical reactions that do not require the presence of oxygen.

Anaerobic organisms are those which can (and often must) live in environments that lack oxygen.
