Answer:
1. Halophilic archaebacterium
2. Methanospirillum hungatei
3. Thermophiles
4. Methanogens
5. Halophiles
Explanation:
Halophilic Archaea (or Haloarchaea) thrive in environments with salt concentrations approaching saturation, such as natural brines, alkaline salt lakes, the Dead Sea and marine solar salterns.
A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). Many thermophiles are archaea, though they can be bacteria. Thermophilic eubacteria are suggested to have been among the earliest bacteria.
Methanogens, microorganisms in the domain Archaea, use hydrogen as their energy source and carbon dioxide as their carbon source, to metabolize and produce methane, also known as natural gas. ... Methanogens are anaerobic, so they they don't require require oxygen.
The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga Dunaliella salina and fungus Wallemia ichthyophaga.
