  4. . There is a wide diversity in living organisms in our biosphere. .Now a question that arises in our minds is: Are all living organisms made of the chemicals, i.e., elements and compounds? You have learnt in chemistry how elemental analysis is performed. If we perform such an analysis on a plant tissue, animal tissue ora microbial paste, we obtain a list of elements like carbon, hydrogen, oxygen and several others and their respective content per unit mass of a living tissue. If the same analysis is performed on a piece of earth's crust as an example of non-living matter, we obtain a similar list.

  5. Carbohydrates Proteins What are the differences between the two lists? In absolute terms, no such differences could be . All the elements present in a sample of earth's . However, a closer examination reveals that the made out. Lipids Nucleic Acids crust are also present in a sample of living tissue. relative abundance of carbon and hydrogen with respect to other elements is higher in any living organism than in earth's crust.
