B
Digestion
C
Absorption
D
Assimilation
E
Egestion
Explanation: 

Detailed explanation-1: -Assimilation is the process of absorption of vitamins, minerals, and other chemicals from food as part of the nutrition of an organism. In humans, this is always done with a chemical breakdown (enzymes and acids) and physical breakdown (oral mastication and stomach churning).

Detailed explanation-2: -It is the movement of the digested food molecules into the cells of the body from where they are used. The liver is important in assimilation. For example, glucose is used in respiration to provide energy, and also amino acids are used to build new proteins.

Detailed explanation-3: -Using a process called endocytosis, cells ingest nutrients, fluids, proteins and other molecules.

Detailed explanation-4: -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.

Detailed explanation-5: -Absorption-It is the process of absorbing simple water-soluble fragments into bloodstream. Assimilation-It is a process of carrying absorbed simple molecules to different organs of the body by blood vessels to build complex substances like proteins.
