English Grammar 1) A desert is one of the most extreme landscapes 2) nature has to offer. This mystical place is the home for many living organisms, 3) which have adapted to the beauty and also 4) to the lack of elements including water. Approximately one-fifth of the earth is a desert, and it contains numerous of vegetation that have the ability to survive there.] 1. shouldn’t this be replaced with ‘deserts are’ to make the sentence more generalized? 2. It appears ‘that’ is omitted in between ‘landscapes’ and ‘nature'. Can explain why? 3. why ‘comma’ is needed before ‘which’? Thought ‘which’ refers to the ‘living organisms’ and the comma is not necessary. 4. can this ‘to’ be removed? Isn’t ‘the lack of~’ is linked to ‘adapted to’ already? Thanks in advance to whoever can shed light on the above questions, and if anything else to highlight!!.
