An amoeba is a single-celled organism that feeds on algae, plants cells, bacteria. when an amoeba feeds, it first makes contacts with the food particle. next, the amoeba starts to surround the particle. once the particle is completely engulfed, it is surrounded by a layer of the amoeba’s membrane, forming a vesicle. the ph in the vesicle is then lowered and the contents are degraded. what type of transport is involved in this process?

The answer is; endocytosis

This is a form of active transport that enable cells to import large particles that cannot pass across the membrane. It is a bulk transport system.  The opposite of endocytosis s exocytosis where the cell expels large particles to the outside of the cell.
