The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use.
Food is broken down into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.
Glucose is taken in by the cells of the body and through the process of cellular respiration is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.
Answer:
The condition of the Earth had to become favourable before it could support any form of life.
The formation of the different layers around the earth like the ozone layer was necessary before life could originate. Primitive species such as some prokaryotes were able to live in hydrothermal conditions during the initial times. With the passage of time, as the concentration of oxygen increased due to photosynthetic prokaryotes, situations became favourable for eukaryotic organisms to arise.
