Detailed explanation-1: -The organic compounds which are the main source of energy in any living being are lipids and carbohydrates. Carbohydrates are nutrients that are used frequently and get converted into energy.

Detailed explanation-2: -Answer and Explanation: ATP is an organic compound that is the main source of energy for all living systems. Certain researchers prefer to call glucose the main source of energy, but glucose is catabolized into energy. Basically, there are four sources of energy: carbohydrates, lipids, proteins and nucleic acids.

Detailed explanation-3: -Carbohydrates are organic molecules that include carbon, hydrogen, and oxygen atoms. These are the key compounds in providing energy. The digestion of carbohydrates requires slightly less time as compared to proteins and fats. Carbohydrates breakdown into glucose molecules with the action of enzymes.
