The Amazon

                   The Amazon is part of the rainforest biome because like other rainforests it is rich with nutrients and animals. It is said that there are between 40-100 different species in every 2.5 acres.is one of the world's greatest natural resources. Because its vegetation continuously recycles carbon dioxide into oxygen, it has been described as the "Lungs of our Planet". About 20% of earth's oxygen is produced by the Amazon rain forest.The Amazon rain forest is the drainage basin for the Amazon River and its many tributaries. The northern half of the South American continent is shaped like a shallow dish. About 1,100 tributaries, seventeen of which are over 1,000 miles long, drain into this depression. The world's largest tropical rain forest, Amazons covers more than half of Brazil.The canopy of Amazons is less studied than the ocean floor. Scientists believe that the canopy may contain half of the world's species. Over 500 mammals, 175 lizards and over 300 other reptiles species, and one third of the world's birds live in Amazons. The Amazon Rain forest consists of layers or communities.  Each layer has unique ecosystems, plants, and animals adapted to that system.High temperatures and the amount of rain are the same throughout the year in Amazons. The climate is warm and humid, with average temperatures around 79° F. The difference between day and night time temperatures is greater than those between seasons. The Amazon is defined by its weather. It is a rain forest — this translates to between 70 to 100 inches of rain yearly. Like any other tropical rainforest, it's hot and humid throughout the year, with an average annual temperature of 27°C (80.7°F).
