The primary component of the Amazon Rainforest is the Amazon River, which is the largest river by discharge volume of water in the world. The rainforest itself supports an incredibly rich biodiversity, housing millions of species of plants, animals, and microorganisms, many of which are not found anywhere else. This ecosystem plays a crucial role in regulating the global climate by absorbing carbon dioxide and producing significant amounts of oxygen. Its conservation is vital due to ongoing threats like deforestation and climate change.
