Answer:
Subsystems
Step-by-step explanation:
The elements of a system form a whole and can be concepts, objects or subjects; these elements can be living, non-living or both simultaneously, as well as ideas, be they from the field of ordinary, scientific, technical or humanistic knowledge. Ideas cannot be conceived as loose or independent of context or
system in which they are inserted. The interaction between the elements and their organization is what makes the system work.
The systemic approach "admits the need to study the components of a system, but does not limit itself to this. It recognizes that systems possess characteristics that their parts lack, but it aims to understand these systemic properties in terms of the parts of the system and their interactions, as well as in terms of circumstances
environmental. In other words, the systemic approach invites us to study the composition, the environment and the structure of the systems of interest
Every system is or can be part of a larger system that we can call supersystem, metasystem, etc. (that is, or may be, a subsystem) or be composed of subsystems, these are nothing more than smaller systems, which at their time may be composed of even smaller ones, and so we could go on until to reach the most elementary components of everything in the universe. The concept system is valid from a cell to the universe considered as a systems.
