Amoeba nutrition involves five steps :
1. INGESTION
Ingestion involves taking in of food.
Amoeba do not have mouth, therefore food intake may take place from any part of the body, but it usually takes place at the advancing end i.e., pseudopodia. This process of obtaining food is called phagocytosis.
2. DIGESTION
Digestion is the breakdown of complex food molecules into simpler molecules through a series of chemical reactions carried out by various enzymes.
In Amoeba, the food digestion occurs within the food vacuoles which, thus, act as temporary stomach. Digestive enzymes secreted by the cytoplasm are stored in the cytosomes. A lysosome full of enzymes fuses with each food vacuole and converts it into diffusible form. Enzymes reported for amoeba include : amylase, which converts starches to sugars, protease, which breaks proteins to amino acids, lipase, that changes fats to fatty acids and glycerol.
3. ABSORPTION
Absorption means taking up digested nutrient molecules into the cells of living organisms.
In Amoeba, the soluble foods resulting from digestion diffuse through the food vacuoles into the surrounding cytoplasm. As absorption proceeds, the food vacuoles decrease in size till only the indigestible matter is left in them.
4. ASSIMILATION
The absorbed food is synthesised into protoplasm and this is known as assimilation. Some food is synthesised into storage products like glycogen and fats. Synthesis is aided by enzymes.
5. EGESTION
The removal of the undigested food is known as egestion.
In Amoeba, egestion may occur in any part of the body. The indigestible matter left in the food vacuoles is denser than the surrounding endoplasm. Such vacuoles finally come in contact with the plasmalemma. The plasmalemma ruptures at this point, and the indigested food is thrown out. Plasmalemma soon gets repaired to prevent the outflow of the endoplasm.
What else can I help you with?
When an amoeba engulfs a particle of food a blank is formed?
When an amoeba engulfs a particle of food, a food vacuole is formed. This vacuole encases the ingested particle, allowing the amoeba to digest the food with enzymes. The nutrients released from digestion are then absorbed into the amoeba's cytoplasm for use.
What stores food in amoeba?
Food is stored in food vacuoles within an amoeba. When an amoeba engulfs food particles through phagocytosis, the food vacuole forms around the ingested material. Enzymes then break down the food inside the vacuole for digestion.
Where in Amoeba does digest its food?
Amoeba digests its food primarily in the food vacuole. When the Amoeba engulfs its prey through a process called phagocytosis, the prey is enclosed in a food vacuole where enzymes break down the food into simpler substances. These nutrients are then absorbed into the cytoplasm for the Amoeba to use. The waste products are eventually expelled from the cell.
In an amoeba a small cavity within the cytoplasm that stores food is called what?
The small cavity within the cytoplasm of an amoeba that stores food is called a food vacuole. This structure helps the amoeba digest and break down food particles for energy.
How does the amoeba obtain oxygen and carbon dioxide?
An amoeba lives in an aqueous environment; some oxygen from the air will normally dissolve into the water (or, oxygen is released by plants living in the water) and oxygen will enter the amoeba by the process of diffusion.
What will happen to the body if blood fails to circulate?
The person will die if the blood does not circulate. Blood is necessary to supply food and oxygen to the body.
How amoeba die?
Amoeba can die if they lack oxygen. They need it.
How does food storage and digestion take place in amoeba?
The digestion of food in Amoeba takes place in the food vacuole. :)

How do the amoeba get their food?
AMOEBAS use pseudopods to get food...
How does amoeba obtain it food?
Amoeba has flexible cell membrane. It enables amoeba to engulf in food by the process called endocytosis.

What protist changes shape constantly and flows around its food to engulf it?
Amoeba
What does the Food Vacuole do in the Amoeba Cell?
The food vacuole is formed by the outer membrane of the amoeba after phagocytosis, digestive enzymes then enter the food vacuole which digest the food that was recently taken in by pseudopods.
