Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb. Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.<span>

The first one according to the graph
It is an example of Passive Transport because the process of Osmosis is where water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, little energy is required to carry out this process.
The cell wall causes them to have different shapes because it’s flexible.
