write the nutrution methods in amoeba and paramecium
Answers
Explanation:
In Amoeba food is digested in the food vacuole by digestive enzymes. These enzymes break down the food in to small and soluble molecules by chemical reactions. In case of Paramecium, hair like structures called cilia helps to sweep the food particles from water and put them in to mouth.

Process Of Nutrition In Amoeba
The different processes involved in holozoic nutrition in amoeba are:
Ingestion
Ingestion is the process of taking in the food into the body either by swallowing or absorbing it. Amoeba pushes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis.
Digestion
Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules. In amoeba, the food vacuoles are transported deeper into the cell and with the help of the digestive enzymes, the large insoluble particles are broken down to the simplest molecules.
Absorption
In this process of absorption, the nutrients from the digested food material are absorbed into the cell’s cytoplasm by leaving behind the undigested particles. This process is called diffusion. The excess food is stored in the form of glycogen and lipids.
Assimilation
Assimilation is the process of obtaining energy from the absorbed food molecules. In amoeba, absorbed food molecules are utilized for producing the energy required to carry out different life processes within the cell.
Egestion
Egestion is the process of excretion of undigested food material. In amoeba, this process is carried out by rupturing the cell membrane to remove the undigested food material from its body.
nutrution methods in paramecium
In holophytic nutrition organisms synthesize complex organic compounds by photosynthesis.
In saprophytic nutrition organisms lives on dead organic matter.
Saprozoic nutrition is living on decayed organic matter.
Holozoic nutrition is a method of nutrition that involves the ingestion of liquid or solid organic material, digestion, absorption and assimilation of it to utilize it. Paramoecium shows holozoic nutrition.
