Chemosynthesis dictionary definition | chemosynthesis …

Paleontologists have recently proposed that the very first life on Earth was chemosynthetic bacteria. Conditions on the young planet at the time of the oldest fossils had much in common with the harsh conditions found at hydrothermal vents. Without chemosynthesis, our planet might well be little more than a lifeless rock.

Deep-sea chemosynthetic bacteria are attracting the attention of a wide range of scientists interested in their commercial potential. Biochemists intrigued by the ability of these tiny, delicate looking creatures to turn toxic chemicals into harmless compounds, hope to use such bacteria to clean up hazardous waste. Chemists seek to isolate the enzymes that allow chemosynthetic microbes to function under extremely high temperatures and put them to industrial use.

It also means that the process does not occur at night.♦ ChemosynthesisThe process takes place without the help of any light source.

"I'm not suggesting these animals are going to be imminently effected by climate change, but that they are not completely immune to what happens at the surface," he said.



In a process called chemosynthesis, specialized bacteria create energy from the hydrogen sulfide present in the mineral-rich water pouring out of the vents.

Proper usage of the word chemosynthesis.

…atmosphere has been removed by photosynthesis, chemosynthesis, and weathering

Chemosynthetic communities are also found in marine settings other than hydrothermal vents. At so-called cold-seeps, where tectonic activity squeezes mineral water out of the ground and around sea bottom petroleum deposits, methane, ammonia, and hydrogen sulfide are released. Bacteria use these compounds to make organic molecules, which support a web of symbionts, carnivores, and scavengers.

This is because, the energy source as well as the place of occurrence in both is different.

Photosynthesis and Chemosynthesis form our basis of existence on Earth.

Other cold seeps and ‘chemosynthetic biological communities’ have been found in the Gulf of Mexico, the Monterey Canyon off the coast of California, US, and off the coast of Alaska, US.

But life based on chemosynthesis is also precarious. The hydrothermal vents—the source of life-sustaining chemicals—can be extinguished at any time by earthquakes, lava flows, or rock falls. Many vents close after a few months or years, and few seem to survive more than a couple of decades. Once the supply of chemicals stops, the bacteria die and the rest of the fauna either migrates or perishes.

Chemosynthesis vs. Photosynthesis

Despite the total darkness, crushing water pressure, and temperatures that swing from above boiling to near freezing, life is good at hydrothermal vents thanks to chemosynthetic bacteria. Vent faunas have both large biomass and high diversity—over 300 species of animals have been found at vents, most living nowhere else on the planet.

The most amazing part of this find was that science had found organisms whose primary energy source was not the sun. It was previously thought that life depended on photosynthesis, converting sunlight to energy. This new find spured questions about how life arose on planet earth. Could it have started through chemosynthesis?

Deep Sea vents: Chemosynthesis, the basis of life in the deep sea
A remarkable find when submersables starting probing the deep sea was the presence of extraordinary abundance of life around mid-ocean vents. Previously, scientists believed that little lived at these emense depths. The only food that would have been avaliable was through dead animals floating down from the surface waters. So what was this abundance sustaining itself on?
