Answer:
Amoeba obtain its food by the process of phagocytosis. It
literally means 'cell eating'. It is a common method of feeding among the
Protozoa and lower Metazoa .
It is also the way in which white blood cells (leucocytes)
engulf cellular debris and uninvited microbes (viruses and bacteria) in the
blood. In the phagocytosis, an area of the plasma membrane, coated initially
with actin-rnyosin, forms a pocket and engulfs the solid material (e.g.,
bacteria, debris).
The membrane-enclosed vesical, phagosome, then detaches
form the cell surface (plasma membrane) into the cytoplasm where its contents
are digested by lysosomal enzymes.
