Answer: True.
By phagocytosis, amoebas are capable of feeding and this is a very useful mechanism in the general feeding structure of the amoeba. Amoebas are non-selective in their general nutrition as they will literally eat whatever they can.
Generally, amoeba feeds on other microscopic organisms like bacteria and one-celled algae. To feed, the cytoplasm of the amoeba goes around the prey and then engulfs it, coupled with a drop of water found in the food vacuole. Enzymes are produced and this helps in breaking down the food substance engulfed. This process is known as phagocytosis.
