Question

In which location would you expect oxygen concentration to be the lowest?

Answer 1

As we travel to the higher altitude the level of oxygen decreases. It is lesser on mountains like himalayas compared to our surroundings.

Answer 2

Unlike any other living organisms or animals we need oxygen to complete our respiratory procedure.

We collect our respiratory oxygen from our surrounding's atmospheric air.

This air amount in the atmosphere will decrease as we go to the higher altitudes.

So the mountain regions in the higher altitudes have the lowest oxygen concentration.
