Final answer:
The correct answer is a chemoorganoheterotroph, which is a bacteria that obtains both energy and carbon from organic compounds and uses chemical means for ATP production.
Step-by-step explanation:
A bacterial species that needs to take in pre-formed organic carbon compounds for its carbon source and uses inorganic chemical compounds for ATP production is known as a chemoorganoheterotroph. These bacteria are considered heterotrophs because they depend on organic compounds obtained from other organisms for both energy and carbon. Unlike photoautotrophs (like plants and cyanobacteria) and chemolithoautotrophs that can use inorganic carbon sources, chemoorganoheterotrophs must consume organic building blocks that they cannot synthesize themselves.
