Who actually Largest Contributor to Oxygen To Earth?

You know who it is?yap answer is Plankton. Phytoplankton in particular is
Plankton are defined as any drifting organisms that live in the pelagic zone (upper part) oceans, seas, and bodies of fresh water. Plankton widely regarded as one of the most important organisms in the world, because of a provision of food for aquatic life.
For most sea creatures, plankton is their main food. Plankton consists of the remains of marine animals and plants. Small size. Although including a kind of living matter, plankton do not have the strength to fight the current, tide or wind carry her away.
Plankton live on the coast where he got the supplies of mineral salts and sufficient sunlight. It is important to allow it to continue to live. Given the plankton into fish food, not surprising that there are a lot of fish on the coast. That is why active fishing activities carried out in the region.
In addition to the remains of animals, plankton are also created from plants. When viewed under a microscope, plant elements can be seen in the plankton algae. Some sea creatures that eat plankton are like rocks, shells, and whales.
Plankton are organisms which accounted for 80% of the oxygen that exist on this earth. with the ability to produce a bubble-gelembun berespisari oxygen contained in the ocean, oxygen is released into the air and into a gas that we can enjoy now
Scientists from the United States found plankton can indirectly create clouds that can withstand most harmful sunrays. So that plankton can help slow the process of global warming.
Dierdre Toole of the Woods Hole Oceanographic Institution (WHOI) and David Siegel of the University of California, Santa Barbara (UCSB) are two researchers.
The study, funded by NASA reveal when the sun is shining on the sea, the top layer of the sea (about 25 meters above sea level) heats up, causing a high enough temperature difference to the marine layer underneath. Upper and lower layers are separated and not mixed with each other.
Plankton live in the upper layers, but the nutrients needed by plankton there is more in the lower layers of the ocean. Therefore, plankton are malnourished.
Due to malnutrition conditions coupled with the hot water temperature, plankton stressed so more vulnerable to ultraviolet rays that can cause damage.
Because susceptible to ultraviolet rays, plankton try to protect themselves by producing substances dimethylsulfoniopropionate (DMSP), which serves to strengthen the walls of their cells.
This substance decomposes into water if the substance will be dimethylsulfide (DMS). DMS then detached itself from the sea surface to the air.
In the atmosphere, DMS reacts with oxygen to form sulfur component type. DMS sulfur components were then attached to each other and form small particles such as dust. These tiny particles are then facilitate water vapor from the ocean to condense and form clouds.
So, indirectly, plankton help create clouds. Clouds are formed causing the less ultraviolet light reaching the surface of the sea, so that plankton were freed from ultraviolet rays disorder.
This process actually has several years studied in the laboratory by scientists, but only this time the natural processes can be studied.
Cloud caused by the plankton, believed to slow the process of global warming, as well as having a large effect tehadap Earth's climate. However, to prove this, further research remains to be done careful.
Research conducted in the Sargasso Sea, off the coast of Bermuda also find it surprising that the DMS particles can decompose naturally in the air after only three to five days. In fact, carbon dioxide in the air, can last up to decades.
