Content: Thermophiles are heat-lovers and live in places such as deep sea thermal vents and hot springs. In Greek, the term 'therm' means 'heat,' such as in 'thermometer' and 'thermal underwear,' and 'philos' means 'lover.' The next group of archaebacteria are called halophiles and they are salt lovers. In Greek, the word 'halo' means 'salt,' and we already know that 'philos' means 'lover.' The last group is the methanogenes, which use carbon dioxide and hydrogen to make methane. They are found in marshes, swamps, sewage treatment facilities and even in the guts of cows. Domain Bacteria
The second group of prokaryotes is that with which you are more familiar. The kingdom eubacteria are true bacteria. They have countless roles, including decomposition and recycling of nutrients, digestion and disease. Eubacteria are often involved in symbiotic relationships with other organisms.
