A) Amazon rainforest
The Amazon rainforest is known for its high biodiversity, which contributes to its resilience to environmental changes. A diverse ecosystem can often better withstand stressors such as climate change, disease, and habitat disturbance because different species can fulfill various ecological roles. In contrast, ecosystems with lower diversity, such as a storm water pond, mountain meadow, or Arctic tundra, may be more vulnerable to changes due to their more limited variety of species and interdependent relationships.
