The Amazon Rainforest is the largest equatorial forest in the world. It extends across nine territories in South America, with approximately 62% of its area located in Brazil. The Amazon Rainforest is home to enormous biodiversity, consisting of millions of species of animals and plants, many of which have not yet been catalogued. It is important for the population that lives there and depends on it, as well as for the Earth's climate.
Average annual temperatures range between 22 and 28 °C and air humidity can exceed 80%. Another characteristic is the high rainfall index, which varies between 1,400 and 3,500 mm per year.
The soil of the Amazon rainforest is considered poor, with a thin layer of nutrients. However, the humus formed by the decomposition of organic matter, i.e. leaves, flowers, animals and fruits, is rich in nutrients used for the development of species and vegetation in the forest.
