Process of Nutrition in Amoeba:
Amoeba obtains its food through a process called phagocytosis. Here is a step-by-step explanation of how nutrition occurs in amoeba:
- Ingestion: Amoeba engulfs its food by extending its pseudopodia around the prey.
- Digestion: The food vacuole containing the prey fuses with lysosomes, releasing digestive enzymes that break down the food particles.
- Absorption: The digested nutrients are absorbed by the cell through diffusion.
- Egestion: Undigested particles are expelled from the cell through exocytosis.

How Paramecium obtains its food:
Paramecium is a ciliated protozoan that obtains its food through a process called filter feeding. Here is how paramecium obtains its food:
- Cilia: Paramecium uses its cilia to create water currents that sweep food particles into its oral groove.
- Oral Groove: Food particles are directed into the oral groove, where they are engulfed by the cell membrane.
- Food Vacuole: The food particles are enclosed in a food vacuole.
- Digestion: Lysosomes release enzymes into the food vacuole to digest the food.
- Absorption: The digested nutrients are absorbed by the cell.
- Egestion: Undigested particles are expelled through the anal pore.
By following this process, paramecium is able to obtain the nutrients it needs for survival.
