Describe nutrition in amoeba

Amoeba is an important protozoa found in fresh water. It feeds on microscopic plants and animals present in water. The mode of nutrition in amoeba is Holozoic. And the process of obtaining food by amoeba is called phagocytosis. The different processes involved in the nutrition of amoeba are:
1. Ingestion: Ingestion is the process of taking food in the body.
2. Digestion: Digestion is the process of breaking the large and insoluble molecules in small and water soluble molecules.
3. Absorption: The food digested by digestive enzymes is then absorbed in the cytoplasm by the process of diffusion.
4. Assimilation: During this step the food absorbed by the cytoplasm is used to obtain energy, growth and repair. This process of utilizing absorbed food for obtaining energy, repair and growth is called assimilation.
5. Egestion: When a sufficient amount of undigested food gets collected in the food vacuole, it is thrown out of the body by rupturing cell membrane. The process of removal of undigested food from the body is called egestion.
