Question

Explain the process of ingestion digestion and excretion of food in amoeba

Answer 1

the process of taking in food by an organism is called ingestion.
digestion is the mechanical and chemical breakdown of food into simple , soluble substances.
after the food gets digested in the food vacuole , the digested food gets absorbed into by the amoeba whereas the undigested food is thrown out of the body from the food vacuole itself . this process is called egestion.
.

Answer 2

Answer:

Ingestion -

Ingestion is the process of taking in the food into the body either by swallowing or absorbing it. Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis.

Egestion -

Egestion is the process of excretion of undigested food material. In amoeba, this process is carried out by rupturing the cell membrane to remove the undigested food material from its body.
