142 BIOLOGYT here is a wide diversity in living organisms in our biosphere. Now aquestion that arises in our minds is: Are all living organisms made of thesame chemicals, , elements and compounds? You have learnt inchemistry how elemental analysis is performed. If we perform such ananalysis on a plant tissue, animal tissue or a microbial paste, we obtain alist of elements like carbon, hydrogen, oxygen and several others andtheir respective content per unit mass of a living tissue. If the same analysisis performed on a piece of earth s crust as an example of non-living matter,we obtain a similar list. What are the differences between the two lists?
