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 It decrease in size as the water is withdrawn and its content first become acidic(pH 5.6) and then alkaline(pH 7.3).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.

Amoebas obtain nutrition by engulfing their prey with their pseudopods, forming a food vacuole. Digestive enzymes are then secreted into the food vacuole to break down the prey into nutrients which can be absorbed by the amoeba.

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.

Is phagocytosis autotrophic nutrition or heterotrophic nutrition?

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


How amoeba takes up food describe process with diagram?

Amoebas take up food through a process called phagocytosis. The amoeba extends its pseudopodia (false feet) around the food particle, forming a food vacuole. Digestive enzymes are then released into the vacuole to break down the food for absorption. The diagram would typically show the movement of the pseudopodia engulfing the food particle and the formation of the food vacuole.


An amoeba engulfs food by?

surrounding it with its cell membrane, forming a food vacuole. The food vacuole then fuses with lysosomes containing digestive enzymes, which break down the food into nutrients that can be absorbed by the amoeba for energy.

What type of nutrition is found in amoeba?

Amoebas obtain nutrition through phagocytosis, where they engulf and digest food particles such as bacteria, algae, and organic debris. They absorb nutrients across their cell membrane after breaking down the ingested material. Amoebas are capable of obtaining nutrients in a variety of environments due to their versatile feeding strategy.
