Introduced species
Ecosystems are complex systems that are in dynamic equilibrium with constant interactions between their parts.
When a new species is introduced, new interactions will occur, generating new components of the system and also competing with the previous interactions between the species already present in the system, which normally ends up generating an imbalance in the ecosystem mentioned, i.e a disruption in it.
