How does the introduction of invasive species such as the brown tree snake upset the stability of an ecosystem?

The introduction of invasive species like the brown tree snake can disrupt ecosystem stability by preying on native species, leading to population declines or extinctions. This predation can alter food webs and resource availability, affecting other organisms that rely on the prey for survival. Additionally, invasive species often compete with native species for resources, further destabilizing the ecosystem and reducing biodiversity. Ultimately, these changes can have cascading effects, impacting ecosystem functions and services.
