Best answer

Amoeba shows holozoic nutrition which is comprised of Ingestion, Digestion, Absorption, Assimilation and Egestion.

Ingestion: 

  • Ameoba traps food particles through finger like projections called as pseudopodia. 
  • Pseudopodia present outside its body and helps in taking food along with water 

Digestion: 

  • Food vacuoles are made after ingesting the food. 
  • Enzymes are released in the food vacuole for digestion. 

Absorption

After digestion, nutrients enter the cytoplasm through osmosis.

Assimilation

Nutrients are utilized by the cell for various purposes

Egestion

  • Food vacuole goes near the cell membrane to empty its contents outside the cell.
  • This results in expulsion of waste materials from the cell.
