Rainforests are home to two-thirds of all the living animal and plant species on the planet. It has been estimated that many hundreds of millions of new species of plants, insects and microorganisms are still undiscovered. Tropical rain forests are called the "jewels of the earth", and the "world's largest pharmacy" because of the large amount of natural medicines discovered there. Tropical rain forests are also often called the "Earth's lungs", however there is no scientific basis for such a claim as tropical rainforests are known to be essentially oxygen neutral, with little or no net oxygen production.[1].[2]
Despite the growth of vegetation in a rainforest, the actual quality of the soil is often quite poor. Rapid bacterial decay prevents the accumulation of humus. The concentration of iron and aluminium oxides by the laterization process gives the oxisols a bright red color and sometimes produces minable deposits (e.g. bauxite). On younger substrates, especially of volcanic origin, tropical soils may be quite fertile.

It is a very dense forest where it rains many inches per year and grows very quickly. I lived in the Ecuador jungle for 12 years and have Sean fence post actually sprout and grow. The plants are in control and when u make a road through it u will spend much time trying to keep it open.

neither do I yet I unquestionably have a computing gadget & i recognize the thanks to Google. Rain forests are forests characterised by technique of extreme rainfall, with definitions putting minimum familiar annual rainfall between 1750-2000 mm (sixty 8-seventy 8 inches). Rain forests are domicile to 2-thirds of each of the residing animal and plant species in the international. it truly is been envisioned that many 1000's of tens of millions of species of flowers, insects and microorganisms are nevertheless undiscovered. Tropical rain forests were referred to as the "jewels of the Earth," and the "international's greatest pharmacy," because of the large form of organic drugs got here across there. The undergrowth in a rain woodland is constrained in a lot of parts by technique of the shortcoming of image voltaic at floor aspect. This makes it conceivable to stroll by the woodland. If the leaf cover is destroyed or thinned, the floor under is quickly colonized by technique of a dense, tangled develop of vines, shrubs and small timber referred to as a jungle. both styles of rain woodland are: Tropical rain forests are rain forests contained in the tropics & Temperate rain forests are rain woodland in temperate areas
