The Sumatran rainforest ecosystem is a rich and diverse habitat located on the island of Sumatra in Indonesia. It is home to a wide variety of plant and animal species, including endangered species like the Sumatran orangutan and the Sumatran tiger. This ecosystem plays a crucial role in regulating the global climate by absorbing carbon dioxide and producing oxygen. The rainforest is characterized by its dense canopy, which provides shelter and food for many organisms. It also features numerous rivers and streams that support aquatic life. However, the Sumatran rainforest faces significant threats from deforestation, illegal logging, and agricultural expansion, which endanger its biodiversity and ecological balance.
