Explanation

Thermophiles live in very hot places, typically from $60{^\circ}\ to\ 80{^\circ}C.$ many thermophiles (some eubacteria and archaebacteria) are autotrophs and have metabolism of sulphur. Some thermophilic archaebacteria from the basis of food webs around deep-sea thermal vents, where they must withstand extreme temperature and pressures. Archaebacteria can grow in highly acidic (pH=0.7) and very basic (pH=17) environments.
