what is the importance of oxygen for living beings?
Answers
Explanation:
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Explanation:
Oxygen is a chemically active element, It is the first element of group 16 of the periodic table, It is important for the human and all living organisms as it is used in respiration and combustion of food inside the living cells to produce the energy that necessary for all vital process.
All plants and trees are living beings which take in carbon dioxide and give out oxygen during the daytime. The plants perform two functions, i.e., photosynthesis and respiration. The former function only happens during daytime, whereas the latter functions is a continuous process.
The cellular respiration is a complex biological process that breaks down sugars, fat and proteins and transforms these materials into energy for the functioning of the organism. Oxygen is needed at the end of this process, when electrons liberated in the respiration are transported through the inner membranes of the cells, and the oxygen "attracts" these electrons and makes possible the production of great quantities of chemical energy in the said membranes.
