When involving chemosynthesis, the bacteria become chemoautotrophic.
Chemosynthetic microbes live on or below the seafloor, and even within the bodies of other vent animals as symbionts.
Understanding the Biogeography of Chemosynthetic Ecosystems.
They either have the chemosynthetic bacteria to perform chemosynthesis, or they wait for some type of carcass to slowly drift to the bottom of the ocean.
Other scientists are studying chemosynthetic organisms and communities to find clues in the search for extraterrestrial life. They speculate that chemical reactions could also support life on poorly lit, but geologically active planets and moons, such as Europa.

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.
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.

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.
Travel to a world of perpetual night--the deep ocean hydrothermal vents near the Galapagos Rift where life thrives around superheated water spewing from deep inside the Earth. Discovered only in 1977, are home to dozens of previously unknown species. Huge red-tipped , ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme found near undersea volcanic chains. How is life possible here? In a process called chemosynthesis, microbes at the base of the foodchain convert chemicals from the vents into usable energy. See closeup footage of hydrothermal vents and species in this clip from the IMAX film "Volcanoes of the Deep."

When discussing chemosynthesis vs
But life based on chemosynthesis is also precarious. The hydrothermal ventsthe source of life-sustaining chemicalscan 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 Definition and Examples - ThoughtCo
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?

These organisms are not dependent on sunlight and photosynthesis, but instead rely on chemosynthesis, a process in which certain microbes use chemicals in the vent water to produce energy.
Chemosynthesis | definition of chemosynthesis by …
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 diversityover 300 species of animals have been found at vents, most living nowhere else on the planet.
Chemosynthesis and Photosynthesis
Chemo- means chemical, and as previously stated, synthesis means the process of producing a chemical compound usually by the union of simpler chemical compounds, thus, Chemosynthesis must mean the process of converting chemicals into food.

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.
