Easy!!
diffusion.. because single celled organisms have a large surface area to volume ratio meaning that there exchange surface is large enough to allow efficient diffusion fast enough to keep the cells alive (1 cell.. lol ). they also aren't very active they can rely on diffusion alone to take up water and other important solutes..
Diffusion through osmosis occurs in single celled organisms when they have a lower water potential inside the cell than outside so water flows into the cell (down the concentration gradient) via a partially permeable membrane.
hope that helped

What is the mechanism by which a small single-celled organism could ingest a smaller single-celled organism?
The mechanism by which one small, single-celled organism could ingest a smaller single-celled organism is phagocytosis. Phagocytosis is the process of ingesting particles of a cell.

No, not quite. A bacterium is a single-celled organism, for sure, but not all single-celled organisms are bacteria.
