Escherichia coli (E. coli) is a heterotrophic organism. This means that it obtains its energy and organic carbon molecules from external sources. Specifically, E. coli is a chemoorganotrophic bacterium, meaning it relies on the oxidation of organic compounds for energy and carbon sources. In its natural environment, E. coli typically utilizes complex organic molecules, such as sugars and amino acids, as sources of energy and nutrients. Unlike autotrophic organisms, which can synthesize their organic molecules from inorganic sources such as carbon dioxide, E. coli, and other heterotrophic organisms must acquire preformed organic molecules from their surroundings to meet their metabolic needs.
