Amoeba is a unicellular , omnivore organism that does not possess specialised organ for the process of nutrition .
The mode of nutrition in Amoeba is HOLOZOIC and takes place with the help of pseudopodia ( finger like structure ) .
It engulfs food when it comes in contact with its cell surface by ingestion .
Pseudopodia fuses over food particle to form food vacuole .
Digestion in Ameoba is INTRACELLULAR in nature. Inside the food vacuole, complex food breaks into small soluble molecules , This process is called ABSORPTION .
The absorbed food is further ASSIMILATED by Amoeba to derive energy for growth.
The undigested food material is removed by the cell membrane, which ruptures suddenly at any place and eliminates out the undigested food.
The process of throwing out undigested food is called EGESTION .
