Anaerobic decomposition or anaerobic digestion.
The release of energy from food molecules in the absence of oxygen is called anaerobic respiration. When there is oxygen present it is called aerobic respiration.
Anaerobic digestion
Organisms can obtain energy in the absence of oxygen through a process called anaerobic respiration. This involves breaking down molecules like glucose without using oxygen. Different organisms may use different pathways such as fermentation to produce energy without oxygen.
Oxygen is not use.Oxygen is produced in photosynthesis when breaking of water molecules to obtain electrons.
Fermentation is an energy releasing process that does not require oxygen. Through fermentation, cells can produce energy without the presence of oxygen by breaking down sugars into simpler molecules and generating ATP.
The process in which oxygen is used to produce energy is called cellular respiration. It involves breaking down glucose into ATP molecules, which are the cell's main source of energy. Oxygen serves as the final electron acceptor in this process.
Water molecules separating means they are spreading, or in other words, the water is evaporating. When they are breaking apart, the hydrogen and oxygen are separating.

cellular respiration
The process in which cells produce energy using oxygen is called cellular respiration. This process involves breaking down glucose molecules in the presence of oxygen to produce ATP (adenosine triphosphate), which is the energy currency of the cell.
Cellular respiration is the process that provides energy for cells by using oxygen. It involves breaking down glucose molecules to produce ATP, the cell's main energy source.
