(b) “no vegetation grows”

(ii) (a) “a beautiful place”.

(b) “home of variety of people, animals and plants that have learnt to live under very hot and dry conditions”. I think the description of the specialists is more apt because a desert is not always dry, hot and sandy. It can also be covered with hills.
