A) eubacteria and archaea
B) cyanobacteria and diatoms
C) protists and mosses
D) liverworts and yeasts
Correct Answer: A
Solution :
[a] Thermophiles live in very hot places, typically from 60° to 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 acidic (pH =0.7) and very basic - (pH =11) environments.
