Ecosystems vary in different geographic regions due to factors such as climate, topography, soil composition, and the presence of specific plant and animal species. For example, tropical rainforests have high biodiversity and a dense canopy due to abundant rainfall and sunlight, while deserts have low precipitation and support plants and animals adapted to arid conditions. Mountain ecosystems have distinct zones based on altitude, with different species adapted to varying temperatures and oxygen levels. Overall, geographic regions influence the characteristics and biodiversity of ecosystems in different ways.
