Explain why the marine ecosystem generates a significant fraction of the oxygen in the atmosphere. a) the marine ecosystem generates 32% of the world’s primary producers. b) the organisms in the marine ecosystem converts carbon dioxide to oxygen faster than organisms in other ecosystems. c) sunlight can easily penetrate the marine ecosystem. d) evaporation is higher in the marine ecosystem than any other ecosystem.

Option C

Explanation:

It is believed by the scientist that microscopic marine plant known as phytoplankton have contributed nearly  85 percent of the oxygen to Earth’s atmosphere.

This is so because phytoplanktons have the ability to photosynthesize in the same manner as plants on land to produce oxygen.  

Hence, it can be said that when sunlight  penetrate the marine ecosystem and interact with the  phytoplanktons, it lead to production of oxygen.

Hence, option C is correct.

cells spend most of their time in interphase
