Process Of Nutrition In Amoeba�
The different processes involved in holozoic nutrition in amoeba are:
Ingestion is the process of taking in the food into the body either by swallowing or absorbing it.
Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules

Absorption the nutrients from the digested food material are absorbed into the cell’s cytoplasm by leaving behind the undigested particles. This process is called diffusion.
Assimilation is the process of obtaining energy from the absorbed food molecules
Egestion is the process of excretion of undigested food material
