Answer:
The five steps which occur in the process of nutrition in animals are Ingestion, digestion, absorption, assimilation, and egestion.
Explanation:
Ingestion : the process of taking food, drink, or another substance into the body by swallowing or absorbing it.
Digestion : Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.
absorption :Absorption is a condition in which something takes in another substance. In many processes important in technology, the chemical absorption is used in place of the physical process, e.g., absorption of carbon dioxide by sodium hydroxide – such acid-base processes do not follow the Nernst partition law.
assimilation : the absorption and digestion of food or nutrients by the body or any biological system.
egestion : Egestion is the act or process of voiding or discharging undigested food as faeces. To egest means to discharge undigested material or food.
