Solution

The steps involved in animal nutrition are:

  1. Ingestion - It means taking solid or liquid food inside the body.
  2. Digestion - It is the breaking down of complex insoluble food components into simple soluble substances.
  3. Absorption - It is the process by which soluble soluble digested food passes from alimentary canal into blood and lymph through intestinal villi.
  4. Assimilation - Utilization of absorbed food by different body cells is called assimilation.
  5. Egestion - Elimination of undigested food as faeces is called egestion.
