The most common type of tree in the Amazon rainforest is the Brazil nut tree (Bertholletia excelsa). The Amazon rainforest is incredibly biodiverse, hosting a multitude of tree species, but the Brazil nut tree stands out for its ecological and economic importance. This towering tree can reach heights of up to 50 meters and produces large, hard fruits that contain edible Brazil nuts. These trees play a crucial role in the ecosystem by providing habitat and food for various wildlife. Additionally, the harvesting of Brazil nuts is a significant sustainable industry for local communities, supporting conservation efforts in the region.
