Anerobic bacteria can do it - sometimes you see a canned good that is bulged on both ends - that is a can with anerobic bacteria at work inside, and should be discarded.

What would most likely be using oxygen to break down food would be the cells in humans and other animals in a process called "osmosis" and respiration plays a role in this as well.
Cellular respiration!
carbon dioxide and water
Photosynthesis is the use of sunlight to power the creation of sugars from carbon dioxide and water. Where's cellular respiration is the reaction of sugars and oxygen to create energy. Because the sugar is being broken down by the oxygen, we would consider cellular respiration to be the one that uses oxygen to break down molecules.
anaerobic respiration is the breakdown of food without oxygen.
It is called fermentation.
Anaerobic Respiration

Oxygen is required to break down food in order to get energy from food. Without oxygen, we'd have no energy and would not survive.
The process of breaking down the rock material without changing its chemical composition is called mechanical weathering.
Decomposers are organisms that break down dead or decaying material. They affect oxygen levels by depleting them since they need oxygen to break down material.
the yeast uses anaerobic respiration instead which only needs glucose

Anaerobic decomposition or anaerobic digestion.
