Amoeba is a microphagous feeder, which means that it feeds upon small aquatic organisms like bacteria, flagellates, ciliates and minute food particles. When a hungry Amoeba approaches to some food particle, it produces out its pseudopodia in the form of food cup which engulf the food particle by turning into food vacuole. the food also contain some water. this complete ingestion. the next step is digestion which is faciliated by the lysosomes. A few lysosomes surround the food vacuole and get fused with the membrane to discharge their enzymatic contents(proteases, amylases and lipases)into it. Hence the digestion is intacellular. At this stage the vacuole becomes a digestive vacuole. It decrease in size as the water is withdrawn and its content first become acidic(pH 5.6) and then alkaline(pH 7.3). When the digestion is completed, the digestive vacuole membrane is drawn into numerous fine canals. the soluble food particles are passed into the canals and finally into the surrounding cytoplasm by micropinocytosis. the digested food, water and minerals are absorbed(absorption) into the cytoplasm and circulate in it, through cyclosis where the food is assimilated into new protoplasm or is oxidized to librate energy. the undigested food is egested by exocytosis at the rear end.

Nutrition in amoeba is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. It is an omnivore, feeding on both plants and animals. Its diet includes bacteria, microscopic plants like the diatoms, minute algae, microscopic animals like other protozoa, nematodes and even dead organic matter.
The mode of nutrition in amoeba is holozoic. The process of obtaining food is called phagocytosis. Amoeba feeds on microscopic organisms floating on water. The nutrition involves processes like ingestion, digestion, assimilation and egestion.Process : Amoeba forms pseudopodia to take food. When the tips of
Surrounding the food with pseudopod.
i am not exactly sure but an amoeba eats food particles
according to me the only difference between amoeba and humans is that , that amoeba is a unicellular organism whereas human are multi-cellular organisms ..............hope you like the answer.......... :D
they are amoeba's without shells, pseudopod without tests and rhizopads habitat is marine and fresh water their nutrition is done through phagocytosis

heterotrophic in very basic, general terms: it "engulfs" it's prey. (like an amoeba!)

They use the process called "Engulfing" to produce food inside of there body.

cells are in a amoeba
An amoeba is a protist and a diatom is not
Amoeba
heterotroph An amoeba (as just one example!).
Freshwater amoeba in salt water will have a higher solute content outside of the amoeba. The water in the amoeba will want to move out of the amoeba and into the environment. This will cause the amoeba to shrivel and die.
