What are chemoautotrophs and Chemoheterotrophs?
1. Chemoautotrophs: microbes that oxidize inorganic chemical substances as sources of energy and carbon dioxide as the main source of carbon. 2. Chemoheterotrophs: microbes that use organic chemical substances as sources of energy and organic compounds as the main source of carbon.
What is the difference between Photoautotrophs and Chemoheterotrophs?
Photoautotrophs are microbes get their energy from light and their carbon for inorganic compounds. Chemoautotrophs are microbes that get their energy from chemicals and get their carbon from inorganic compounds. Chemoheterotrophs get their energy from chemicals and carbon from organic compounds.
What is meant by Chemoheterotroph?
/ (ˌkiːməʊˈhɛtərəʊtrəʊf, ˌkɛm-) / noun. biology an organism that obtains its energy from the oxidation of organic compoundsAlso called: chemo-organotroph.
What is the carbon source for a Photoheterotroph?
Photoheterotrophs are heterotrophic organisms that make use of light energy as their energy source. They also cannot use carbon dioxide as their sole carbon source. They use organic compounds from the environment.
What is an example of a Chemoheterotroph?
Most animals and fungi are examples of chemoheterotrophs, obtaining most of their energy from O2. Halophiles are chemoheterotrophs.
What is the main difference between Chemoautotrophs and Chemoheterotrophs which of these groups include bacteria which include organisms that cause human disease?
Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environment. Chemoautotrophs use inorganic energy sources to synthesize organic compounds from carbon dioxide. Chemoheterotrophs are unable to utilize carbon dioxide to form their own organic compounds.

Photoheterotroph/Representative species
What is the energy source for Photoheterotroph?
Photoheterotrophs obtain their energy from sunlight and carbon from organic material and not carbon dioxide. Most of the well-recognized phototrophs are autotrophs, also known as photoautotrophs, and can fix carbon.
What is Photoheterotroph example?
What is a Photoheterotroph in biology?
Photoheterotrophs (Gk: photo = light, hetero = (an)other, troph = nourishment) are heterotrophic phototrophs – that is, they are organisms that use light for energy, but cannot use carbon dioxide as their sole carbon source.
How do chemoautotrophs make energy?
Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environment.
What are some examples of chemoheterotrophic bacteria?
An example of chemoheterotrophic bacteria is a sub-type called lithotrophic bacteria , also known as “rock eaters” or “stone eaters.” These bacteria are found in underground water sources and on the ocean floor where there are both mineral food sources and organic molecules available.
How do chemolithotrophs acquire energy?
Chemotrophs obtain their energy from chemicals (organic and inorganic compounds); chemolithotrophs obtain their energy from reactions with inorganic salts; and chemoheterotrophs obtain their carbon and energy from organic compounds (the energy source may also serve as the carbon source in these organisms).
Is archae a chemoautotroph?
Most chemoautotrophs are extremophiles, bacteria or archaea that live in hostile environments (such as deep sea vents) and are the primary producers in such ecosystems. Chemoautotrophs generally fall into several groups: methanogens, sulfur oxidizers and reducers, nitrifiers, anammox bacteria, and thermoacidophiles.
