Answer 2

Answer:

Absorption. Digested food molecules are absorbed in the small intestine . This means that they pass through the wall of the small intestine and into our bloodstream. Once there, the digested food molecules are carried around the body to where they are needed.

Assimilation is the movement of digested food molecules into the cells of the body where they are used. For example: glucose is used in respiration to provide energy. amino acids are used to build new proteins.
