Biotic and Abiotic Factors

The  Biotic factorsDifference between biotic and abiotic factors are the living components of ecosystems: living things. The term can be used to speak of individuals as each organism that inhabits the system, globally as the total population that inhabits the same area or place, or as a community with a group that has a characteristic or that establishes a relationship.

The biotic factors, by their own definition, are those that have life and then movement, therefore they must acquire energy (carry out a feeding process).

In this way, it can be said that biotic factors are responsible for having an active behavior in the ecosystem, generating relationships through the need for survival (this could be discussed in the case of the human being, who expanded his needs beyond survival itself). It is common for biotic components of an ecosystem to be divided between organisms that produce their own food (usually vegetables), consumers of already produced food (animals), and decomposers of dead animals (some fungi and bacteria ).

Abiotic factors

The abiotic factors have to do precisely with everything that is outside the biotics, that is, everything that gives the ecosystem the characteristics that allow it to generate the life of the species that are related to it. Indispensably these will be elements that lack life, and therefore will not be responsible for changes within the ecosystem. The action of living beings can have different effects on the abiotic factors of the ecosystem, even transforming it: however, since it is these factors that allow life, it is possible that a transformation produced by one species restricts the survival of another. Around the preservation of certain abiotic factors, it is frequent that new relationships are established within the ecosystem. When the modification occurs, or when new organisms enter an already configured system, they may have to go through a process of adaptation to the new conditions.
