Question

why does a deep sea diver and mountainair carry oxygen cylinder on her back?​

Answer 1

Answer:

Explanation:

Divers carry oxygen cylinders with them as the bottom of sea has low levels of oxygen also known as hypoxia. The deficiency of oxygen in bottom waters changes the type of organisms also. They are mostly small and fast growing and can tolerate low concentrations of oxygen. At bottom only bacteria and fungi can survive.
