It is part of the Respiratory Cycle of most living things on Earth.
The biological significance of a DNA molecule is that it: 1) Controls the synthesis of proteins (as well as enzymes because they are also proteins). 2) Is responsible for carrying hereditary characteristics.
I believe it is the role for something (Substance or Being) in nature So oxygen molecules will have the biological role to supply the animal's blood with oxygen
by utilizing oxygen for biological processes without taking any additional oxygen in
Fermentation is a simple biological process that does not require oxygen. It involves the breakdown of sugars into energy in the absence of oxygen, producing substances like alcohol and lactic acid.

Photosynthesis returns oxygen to the environment (undertaken by the biological processes of plants).

It determines the amount of dissolved oxygen that is consumed by aerobic biological microorganisms in water. It is measured by the amount of oxygen that is consumed per liter of sample during 5 days of incubation it is in milligrams.
Oxygen consumption in a biological system can be calculated by measuring the amount of oxygen consumed by the system over a specific period of time. This can be done using techniques such as respirometry, where the decrease in oxygen concentration in a closed system is monitored. The rate of oxygen consumption is then calculated based on the change in oxygen concentration and the volume of the system.
A biological oxygen demand is another term for a biochemical oxygen demand - the amount of oxygen needed by aerobic microorganisms to decompose all the organic matter in a sample of water - used as a measure of pollution.
