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.

a covalent bond, specfically triple bond

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
