Solution

Part 1:Definition of elemental analysis
Elemental analysis is to determine the quantity of a particular element within a molecule or a material.

Part 2: Elements present in living organisms
In all living systems there are 4 basic elements:carbon,oxygen,nitrogen and hydrogen.

Part 3:Elements present in non-living things
Elements like carbon, oxygen, nitrogen and hydrogen are also found in non-living systems like the Earth’s crust. But the relative % weight of carbon and hydrogen is higher in the living system, than in the non-living system.
