It is a biological term for an organism that derives energy and carbon from the oxidation of preformed organic compounds. These include fungi, which do not have chloroplasts to use photosynthesis.

∙ 12y agoChemoautotroph is a specific type organism that is able to make its own "food" or energy source by getting an energy input from inorganic sources.
Troph refers to energy source (nourishment).
Auto refers to self.
Chemo refers, in this case, to an inorganic source of energy to bind carbon.
Plants are generally photoautotrophs, using light energy to bind or fix carbon into a food source (energy source that can be stored).
Heterotrophs must obtain nourishment by metabolizing (eating) other organisms. Examples are rabbits, birds, etc.

How does chemoautotrophs obtain energy?
Chemoautotrophs (or chemotrophic autotroph), in addition to deriving energy from chemical reactions, synthesize all necessary organic compounds from carbon dioxide. Chemoautotrophs generally only use inorganic energy sources. Most are bacteria or archaea that live in hostile environments such as deep sea vents and are the primary producers in such ecosystems. Evolutionary scientists believe that the first organisms to inhabit Earth were chemoautotrophs that produced oxygen as a by-product and later evolved into both aerobic, animal-like organisms and photosynthetic, plant-like organisms. Chemoautotrophs generally fall into several groups: methanogens, halophiles, sulfur reducers, nitrifiers, anammoxbacteria and thermoacidophiles.
What part of the light reactions of photosynthesis is similar to the oxidation of minerals by chemoautotrophs?
The light bar
Unlike photoautotrophs chemoautotrophs obtain energy by?
Photosynthesis for phototrophs, or chemosynthesis for chemotrophs.
Why are chemoautotrophs rare among familiar organisms?
Chemoautotrphs are rare among other familiar organisms because they do not compete well with other organisms and they are not important in the sun-lit, carbon-rich environments which we are familiar with.
Is cyanobacteria chemoautotrophs?
Yes, cyanobacteria are autotrophs. An autotroph is any organism that is able to take inorganic raw material and turn it into organic energy containing molecules.
Are animals chemoautotrophs?
No. We aren't autotrophs at all (one partial autotrophic animal has been found to exist), but no only some archea are chemoautotrophs
Why doesn't photorespiration occur in chemoautotrophs?
Photorespiration doesn't happen because of this spatial separation. Chemoautotrophs are found in the deep sea. Autotrophs make their own food.
Are fish chemoautotrophs?
No, Chemoautotrophs are Microorganisms (Bacteria).Search Chemoautotrophs on Wikipedia for more details.
Do chemoautotrophs need sunlight to survive?
no
Could chemoautotrophs survive on the moon?
Bu no
Where would chemoautotrophs live?
up your nose
Three kinds of autotrophs?
photoautotrophs chemoautotrophs lithoautotrophs
Do chemoautotrophs do photosynthesis?
No they do not .They use chemical energy and CO2
Bacteria that use sunlight as an energy source are considered?
Chemoautotrophs
Are prokaryotes autotrophs?
They can be, Photoautorophs, Photoheterotrophs, Chemoautotrophs or Chemoheterotrophs
Do chemoautotrophs gain energy by oxidizing or reducing substances in their environment?
Yes
What bacteria can be grown in inorganic nutrients and oxidizes ammonia to nitrate ion?
chemoautotrophs.
