of course is essential to all life (Farabee). Photosynthesis also refers to the process that goes in plants, and some bacteria, that turns sunlight into sugar, which can be used
for energy by these living organisms (Farabee). To put the chemical process of photosynthesis simply, "six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar
plus six molecules of oxygen (Farabee). It is truly a beautiful system, as plants take in carbon dioxide, which is the byproduct of human respiration, and release oxygen, which animals
need to survive. Another reason photosynthesis is essential to all life earth is because plants provide the foundations of the food chain. Plants depend on the sun for food.
Herbivores depend on plants for food. Carnivores depend on eating herbivores. Without plants, herbivores die, carnivores die, even humans (who will eat anything) die if there is nothing to eat.
Life itself depends on the energy of the sun which is made available in a form that we can use through photosynthesis and plants. What source of energy than
the Sun might some organism use : At one time, scientists assumed that nothing lived in the deep abyss of the ocean. This was logical. Sunlight cannot penetrate beyond
300 feet of water so how could anything live in the depths of the ocean? In 1977, scientists discovered hot springs on an undersea ridge off the coast of South
America, which exists at a depth of 2.5 kilometers (Hydrothermal). Since this discovery, numerous hydrothermal vents creating these hot springs and their release of various chemicals into the surrounding water--chemicals
that can support life. The assumption that the ocean floor is necessarily sterile because light cannot reach it was proven wrong since scientists found large biological communities around these hydrothermal
