Assimilation (also called anabolism) refers to the process in which organisms convert nutrients obtained from the external environment into their own components and store energy. That is, organisms use energy to synthesize small molecules into large molecules.

Assimilation is an important process in biological metabolism, and its function is to recombine digested nutrients to form organic matter and store energy. Because the material elements in food are stored in the body, it is called "assimilation". The process of transforming substances absorbed from the environment into their own organic substances and storing energy is called assimilation. The types of assimilation include autotrophic and heterotrophic. The process of decomposing organic matter into inorganic matter and then returning to the inorganic environment to release energy is called alienation. The types of alienation include aerobic, anaerobic and facultative anaerobic.

Biology can be divided into autotrophs and heterotrophs by assimilation.

Autotrophic organisms: organisms that can synthesize their own organic matter from inorganic substances belong to autotrophs. Such as cyanobacteria, nitrifying bacteria and green plants.

Heterotrophs: Organisms that can only ingest ready-made organic matter from outside belong to heterotrophs. Such as most animals and fungi.

Generally speaking, digestion is a typical example of assimilation.

The same is true of photosynthesis, because in this process, plants use carbon dioxide and sunlight to make their own food (organic molecules) and store these organic molecules in the plants themselves.

Generally speaking, all higher plants and some lower plants, as well as a small number of bacteria can carry out photosynthesis.

(assimilation)

One of the important concepts in sociology and other disciplines. Assimilation is a physiological concept, which refers to the digestion process of food in the body. Sociology borrows this concept, which refers to the gradual or slow process in which different cultural units merge into a homogeneous cultural unit.

And assimilation

Simply put, assimilation is to turn non-self into self; Alienation, on the contrary, turns itself into a non-ego.

Assimilation is an important process in metabolism, and its function is to recombine digested nutrients to form organic matter and store energy.

Alienation is the catabolism of organisms. It is a process in which organisms convert macromolecules into small molecules and release energy. Breathing is an important process in alienation.

Organisms can be divided into aerobic organisms, anaerobic organisms and facultative organisms according to whether they need oxygen for breathing.

The essence of alienation is that macromolecules in organisms, including protein, lipids and sugars, are oxidized and release energy in the process of oxidation. Part of the energy is absorbed by the reaction of converting ADP into ATP, and ATP is used as an energy storage material for other needs.
