All of the other answer choices are types of extremophiles, organisms that thrive in extreme environments. Archaea is a domain of unicellular microorganisms that include extremophiles such as methanogens, halophiles, and thermophiles. Methanogens are a type of archaea that produce methane gas as a metabolic byproduct. Halophiles are extremophiles that thrive in high saline environments, while thermophiles are extremophiles that thrive in high-temperature environments. Photoautotrophs are organisms that use photosynthesis to produce their own food, but they are not necessarily associated with extreme environments.
