The term biotic refers to the totality of the characteristics that qualify the existence of living organisms (structure, organization, etc.).
The term bïòtico comes from the Latin biotĭcus, in turn derived from the Greek βιωτικός “relative to life”, derived from βιόω “to live”.
In ecology, the factors that determine the characteristics, composition and distribution of life are of two types: abiotic and biotic, to which are then added a third category of factors that are defined as limiting.
A biotic factor is therefore related to life or living organisms and can also take on the meaning synonymous with biological.
In general, therefore, the term biotic, although synonymous with biological, takes on more limited meanings, especially concerning the ecological and biogeographic disciplines. In particular for biotic factors we mean the organisms that act on the vegetation or on other processes: for example, the bacteria that modify the chemical composition of the soil, the parasites, etc.
