Lichens are the smalles living things

Question

True or false if it is false cross out the underlined word and put the correct word in (the underlined word is lichens) 

Answer 1

The statement is FALSE.  Putting in the "correct" word is difficult as there isn't total agreement among biologists as to what actually constitutes the smallest living "thing".  One possible answer would be to put in the word "nanobe" which is believed by many to be the smallest life form.
