what is Amoeba? explain nutrition in amoeba
Answers
Explanation:
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 known as holozoic nutrition. It involves the ingestion, digestion and egestion of food material.
Amoeba does not have any specialized organ for nutrition. Its entire process is carried through the body surface with the help of pseudopodia.
