GEOLOGY

Detailed explanation-1: -Marine plants and algae provide food and shelter to fish and other marine life, but they are not just important to aquatic ecosystems; they provide about 70 – 80 percent of the oxygen on Earth, making them extremely important in our everyday lives as well!

Detailed explanation-2: -Phytoplankton are microscopic marine algae. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.

Detailed explanation-3: -The fact is that 85% of all plant life is found in oceans. Even NASA was stunned in 2011 to find that the waters of the Arctic Ocean, despite being covered by three-foot thick ice, are richer in microscopic marine plants than any other ocean region in the world.

Detailed explanation-4: -From 1, 000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either.
