Answer:
The
mode of nutrition in Amoeba is holozoic.
The various steps involved in the process of nutrition are:
(i) Ingestion: Amoeba ingests food with the help of
its finger-like extensions, called pseudopodia. When a food particle approaches
Amoeba, it forms pseudopodia around it and forms a food vacuole inside
the Amoeba.
(ii) Digestion: Various enzymes from the cytoplasm
enter into the food vacuole and break them down into simple soluble molecules.
(iii) Absorption: The simple soluble food is
absorbed by cytoplasm of Amoeba from food vacuoles through the process of
diffusion.
(iv) Assimilation: Amoeba cell obtains energy from
the absorbed food through respiration. This energy is utilized by Amoeba for
its growth and repair of the body.
(v) Egestion: When a considerable amount of
undigested food gets collected inside Amoeba, its cell membrane ruptures and
throws out the undigested food.
