All animals including human beings need oxygen to survive. Oxygen is required to break down the food we eat into smaller components and produce the energy we need to live and do the activities of daily life like playing or even sleeping! Oxygen also helps in the removal of carbondioxide, an undesired gas, from our body which is produced along with energy during the breaking down of the food we eat into smaller components.
