The basic chemical differences that differentiate between living and non living systems are:
• Living systems are made up of chemical molecules like carbohydrates, proteins, nucleic acids and lipids.

• A genetic program is present in the nucleic acids of living systems
• Living systems take required nutrients from their surroundings for their growth and development. These nutrients are used in the process of metabolism.
