Chemosynthesis :: essays research papers fc

IntroductionSynthesis is the process of producing a chemical deepen usually by the union of simpler chemical compounds. For example, photosynthesis, the word photo means putting together with light. Photosynthesis is the process of converting cheer into food for organic organisms such as plants. Photosynthesis is the basis of life for artificial satellite earth and without it not only would we not be able to produce the fruits and vegetables that we consume, but the food to feed the animals that we eat. Plants absorb this sunlight which in turn makes oxygen in a process called respiration. This delicate cycle is what allows us to nail on this planet. Although much of the life on this planet relies on photosynthesis in one way or another, there is another form of synthesis that is equally as important, chemosynthesis.The deep sea is considered the largest, yet, least-known habitat on earth and covers about two-thirds of the earth. Every year, and every dive down to the mysteriou s depths of the deep-sea bring scientist closer and closer to unraveling the secrets of the unimaginable deep. This is where chemosynthesis takes place because there is no sunlight available in order for photosynthesis to take place.How hydrothermal vents workIn 1977, in the Galapagos Islands, the first hydrothermal vents were found. Using a submersible called the Alvin, scientist were able to explore this disaffect world never known to have existed for the first time. Hydrothermal vents are chimney like structures on the ocean floor that release extremely hot, mineral well-to-do water. This process is called Hydrothermal Circulation. Ocean water seeps into the earth, becoming increasingly hotter as it descends downward. As the water passes through the cracks of the earth, it is becoming enriched with metals and minerals until finally turning to a very acerb fluid. When the super heated water reaches about 700&730F (400&730C), the fluid rises and bursts through cracks in the sea floor. The super heated water mixing with the cold sea water causes a chemical reaction and forms particles of metal sulfide to cloud the water. The pieces of metal settle around the area of the crack, and over time, collect to form the chimneys of murky smokers. One would assume that at the very bottom of the ocean, in 700&730F waters, that nothing could possibly exist here. Surprisingly, over 300 strange and unique species thrive only in these conditions.What lives near hydrothermal vents?
