They mostly feed on diatoms, algae, microscopic organisms and other dead organic matter present in water. The mode of nutrition in amoeba is Holozoic. Nutrition in an amoeba occurs through a process called phagocytosis where the entire organism pretty much engulfs the food it plans on eating up.
- The mode of nutrition in Amoeba is holozoic.
- In Amoeba the process of obtaining food is called Phagocytosis.
- When Amoeba take liquid substance it is called Pinocytosis.
The various process are as follows:
- Ingestion: Amoeba intake food particles by forming temporary finger like projection known as pseudopodia around them.
- Food is encaptured along with lysosome into a bag called food vocuole.
2. Digestion: In Amoeba food is digested in food vocuoles
by digestive enzymes.
3. Absorption: The digested food found in food vocuoles
is absorbed directly into cytoplasm by diffusion.
4. Assimilation: A part of the food absorbed in cell is used
to obtain energy through respiration. The remaining part
is used in growth of Amoeba.
5. Egestion: The undigested food remains in the food
vocuole is thrown out of the body by rupturing cell
membranes.
