What is an Amoeba?
An amoeba is a single-celled organism that is capable of moving and feeding itself. It has a simple shape that can change depending on its environment. Amoebas are found in both fresh and salt water, and some species can survive in extreme conditions.
Mode of Nutrition in Amoeba
Amoeba is a protist and a single-celled organism that lives in water. It has a simple body plan and lacks a true nucleus. Amoeba obtains its food by phagocytosis, a process in which the cell engulfs food particles by extending pseudopods. The food particles are then digested by enzymes in the lysosomes of the cell.
Process of Nutrition in Amoeba
The process of nutrition in amoeba is ingestion of food, digestion of food, absorption of food, and excretion of waste. Amoeba uses pseudopods to engulf food particles. Digestive enzymes break down the food into molecules that can be absorbed into the cells. The absorbed molecules are used to produce energy and to build new cells. Waste products are excreted from the cell.
Ingestion
of a foreign body can cause a number of problems. The most common problems are caused by the body trying to expel the object. This can lead to obstruction of the digestive tract, perforation of the intestinal wall, and sepsis.

Digestion
is the process that the body uses to break down food into smaller pieces that can be used by the body for energy, growth, and repair. The mouth is the beginning of the digestive system. The food we eat is chewed and mixed with saliva. Saliva contains digestive enzymes that break down the food into smaller pieces. The food then travels down the esophagus to the stomach. The stomach churns and mixes the food with digestive juices. The food is then digested and absorbed into the bloodstream. The undigested food is eliminated as waste.
The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The small intestine and large intestine are also called the intestine. The intestine is a long, coiled tube that absorbs the nutrients from the food. The rectum is the last part of the digestive system. The rectum stores the waste until it is eliminated as feces.
Absorption
and emission of light
When light shines on a material, some of it is absorbed by the material. The rest of the light is reflected off the surface of the material.
If the material is a different color than the light that is shining on it, the light that is reflected will be a different color than the light that is shining on it.
If the material is hot, it will emit light. The light that is emitted will be the same color as the light that is shining on it.
Assimilation
Assimilation is the process of absorbing one cultural group into another. It can refer to the gradual process of immigrants adopting the language and culture of the country in which they live, or to the sudden adoption of new cultural values by a majority group in response to a minority group’s presence.
Egestion
The process of passing solid waste out of the body through the anus.
