ameoba is a simple unicellular organism .nutrition in ameoba can be explained under following heading . ameoba is macrophages feeder and feeds upon small aquatic organisms like bacteria, flagellates and ciliates.
INGESTION: when ameoba comes in contact with a good particles it ingests it in the form of a good vacuole by producing pseudopodia around it.
DIGESTION: digestion in ameoba is unicellular. First water is expelled out of good vacuole and then lysosomes encircle the good vacuole and add their hydrolytic enzymes into it. these enzymes digest the food which is then absorbed into the cytoplasm by diffusion and active transport.as the vacuole in the cytoplasm it supplies food to every part of the body.
EGESTION: ameoba has no definite opening for egestion. it's undigested food is egested by exocytosis through any part of its cell membrane.
I hope it will help you☺

Nutrition in Amoeba
These projections then engulf the food, forming a food vacuole. ... The enzymes process and help complete digest of the complex food molecules into simpler substances of soluble nature. After this, the nutrients are absorbed into the body of the amoeba through the wall of the food vacuole.
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:
Nutrition in Amoeba
Ingestion is the process of taking food in the body. Amoeba is a unicellular animal, so it doesn’t have a mouth for ingestion of food. Amoeba ingests the food by encircling it by forming pseudopodia. When the food is completely encircled , the food is engulfed in the form of a bag called food vacuole.
2. Digestion:
Digestion is the process of breaking the large and insoluble molecules in small and water soluble molecules. In amoeba, several digestive enzymes react on the food present in the food vacuoles and break it down into simple and soluble molecules.
3. Absorption:
The food digested by digestive enzymes is then absorbed in the cytoplasm by the process of diffusion. While the undigested food remains in the food vacuole. If a large amount of food is absorbed by amoeba, the excess food is stored in the cytoplasm in the form of glycogen and lipids.
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.
