Ecosystems vary in different parts of the world due to various factors such as climate, geography, soil composition, and the presence of different plant and animal species. For example, tropical rainforests are found near the equator and have high levels of biodiversity, while deserts are characterized by arid conditions and sparse vegetation. Mountainous regions have distinct ecosystems based on altitude, with different species adapted to different elevations. Coastal areas have unique ecosystems influenced by the proximity to the ocean. These variations lead to a wide range of ecosystems around the world, each with their own characteristics and species composition.
