What do you mean by Endocytosis? How does an Amoeba obtain its food? 

Answer: 

The process by which a cell engulfs material to bring it into the cell is called endocytosis. It is a type of active transport.

Endocytosis is of two types: 

Phagocytosis: It refers to the process of engulfing large particles (or cell eating). 

Pinocytosis: it refers to engulfing macromolecules. (or cell drinking) 

For example, Amoeba obtains its food by

endocytosis in which the flexibility of the cell membrane enables the cell to engulf in food and other material from its external environment.
