At various points throughout Earth’s geological history, atmospheric and oceanic oxygen levels have been different than they are today. If future oxygen levels in the ocean become higher than they are today, what effect do you think this will have on the relative frequencies with which ram ventilation or buccopharyngeal pumping are used by aquatic vertebrates? Please explain your answer.

Marine Evolution

Marine habitat is less explored, and hence, its biological diversity is far less known. The marine habitats are not constant due to their shifting nature, while the terrestrial habitats are more stable. Marine biology is the science that deals with the study of diverse marine species, their interactions, and behavioral characteristics.
