Polyethism is the term used for functional specialization of non-reproductive individuals in a colony of social organisms, particularly insects. Division of labour is considered a key aspect of eusociality and can be seen in a variety of forms. In some insects, there are distinct morphological differences among the individuals that decide their ...
The division of labour is the separation of the tasks in any economic system or organisation so that participants may specialise (specialisation).Individuals, organisations, and nations are endowed with or acquire specialised capabilities, and either form combinations or trade to take advantage of the capabilities of others in addition to their own.

The ammonia molecule (NH 3), like the water molecule, is abundant in the universe, being a compound of hydrogen (the simplest and most common element) with another very common element, nitrogen. [51] The possible role of liquid ammonia as an alternative solvent for life is an idea that goes back at least to 1954, when J. B. S. Haldane raised ...
A non-directional, random change in the movement of a molecule, cell, or organism in response to a chemical stimulus, e.g. a change in speed resulting from exposure to a particular chemical compound. chemotaxis A directed, non-random change in the movement of a molecule, cell, or organism in response to a chemical stimulus, e.g. towards or away ...
Herbivores and carnivores are examples of organisms that obtain carbon and electrons or hydrogen from living organic matter. Chemoorganotrophs are organisms which use the chemical energy in organic compounds as their energy source and obtain electrons or hydrogen from the organic compounds, including sugars (i.e. glucose), fats and proteins.

Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. [1]
In economics, the new international division of labour (NIDL) is an outcome of globalization.The term was coined by theorists seeking to explain the spatial shift of manufacturing industries from advanced capitalist countries to developing countries—an ongoing geographic reorganisation of production, which finds its origins in ideas about a global division of labor.
