  2. Absorption – the taking in of substance by cells or membranes
  3. Metabolism – sum of all physical and chemical processes by which a living organism is formed and maintained and by which energy is made available
  4. Storage – some nutrients are stored when not used to provide energy; e.g. carbohydrates are stored either as glycogen or as fat
  5. Elimination – process of discarding unnecessary substances through evaporation, excretion
