    Solution

    Chemo-organotrophs are organisms that obtain energy by oxidizing organic compounds. These organisms rely on organic molecules as both their carbon and energy source. Escherichia coli is an example of a chemo-organotroph because it uses organic compounds (such as glucose) for its energy and carbon source.
