Text Solution

Verified by Experts

The correct Answer is:
A
(a) Thermophiles live in very hot places, with Temperature ranging from `60^(@)-80^(@)C`. Many thermophiles (some eubacteria and archaebacteria) are autotrophs and have metabolisms based on sulphur. Some thermophilic archaebacteria form the basis of food webs around deep-sea thermal vents, where they must withstand extreme temperature and pressures. Archaebacteria can grow in highly acideic (pH = 0.7) and very basic (pH = 11) environments.
