How do invasive species affect the biosphere?

Invasive species disrupt local ecosystems by outcompeting native species for resources such as food, habitat, and water, often leading to declines or extinctions of indigenous populations. They can alter habitat structures and nutrient cycles, which affects biodiversity and ecosystem stability. Additionally, invasive species can introduce new diseases, further threatening native wildlife and plant species. Overall, their presence can significantly impact ecological balance and reduce the resilience of ecosystems to environmental changes.
