Amoeba is a unicellular protist that does not have a definite shape and feeds through phagocytosis, ingesting algae, bacteria, and other protozoa. Digestion occurs intracellularly, with food vacuoles containing enzymes breaking down carbohydrates, lipids, and proteins inside the cytoplasm, and nutrients being absorbed while waste is expelled through the surface of the cell.

3. • Amoeba is a unicellular organism
comes under the kingdom protista in
the class protozoans .
• They does not have any definite
shape.

4. • Their predation of food is through the
process known as phagocytosis.
• Algae , bacteria and small protozoa
are the main food of amoeba

5. • Digestion of amoeba is intracellular
because it takes place inside the body.
• Digestion takes place inside the food
vacuole present in the cytoplasm.
• The food vacuole contains enzymes
that can digest carbohydrates, lipids
and proteins.

7. • The nutrients are absorbed into the
cytoplasm surrounding the food
vacuole.
• The waste materials are expelled
through the body surface.
