Tropical Rainforest


Tropical forest in the world 

I read an article in the BBC page about the Tropical Rainforest. This gives basic information about the weather, cycles of water and nutrients, the soil and some plants that are typical from the rainforest.
The weather in the rain forest is pretty much the same, it rain almost every day and there are two seasons; the rainy season when it is rain a lot every day  and the dry season when the rain is lower. The average temperatures are constant all the year, between 26-28ÂșC.
The cycles of water are affected by the rain and the water that roots take out from the soil. The nutrients are very common at the soil; the hot, damp conditions on the forest floor allow for the rapid decomposition of dead plant material, this provides plentiful nutrients that are easily absorbed by plant roots. However this nutrient disappears when vegetation is removed, the soil become infertile and vulnerable to the erosion.
The rainforest vegetation has some characteristics that help it to survive in the environmental. The article describes 4: 1) the Fam palms: these have special leaves that are good to catching sunshine and water, 2) the Buttress roots is a shallow layer of fertile soil, 3) the Lianas are woody vines that start at ground level and climb up using the trees to get light and 4) the Strangler fig that is the opposite, start in the top of the tree and work down.
 I choose this topic because I really love the rainforest and I think that it’s very interesting. The text is fine and I think that I would recommend. The thing that I like the most was this map
