The text is a transcript of a video class about the Amazon biome, its history, climate, soil, rivers, vegetation and landscapes. The narrator explains the main features and adaptations of the plants and animals that live in different regions of the Amazon, such as the terra firme forest, the varzea, the igapo and the manguezal. He also shows some examples of the biodiversity and ecological interactions in the Amazon, such as the water vine, the samauma tree, the rubber tree and the victoria water-lilies. He ends by saying that he will talk about the animals of the Amazon in the next video.
1. In 1542, a Spanish troop arrived in the Amazon after gold, after the so-called Eldorado Kingdom.

22. The Amazon soil is heavy in nutrients, it's a fertile soil.
23. The Amazon soil is located on the surface of the soil, the nutrients that will infiltrate the soil, that will be directed to the roots of the plants.
24. The Amazon has a very high vegetal biodiversity, when it comes to angiosperms, we have over 20 thousand species.
25. The Amazon has a very high vegetal biodiversity, when it comes to angiosperms, we have over 20 thousand species.
26. The Amazon has a very high vegetal biodiversity, when it comes to angiosperms, we have over 20 thousand species.
