There are three major types of forest
15.tropical rain forest, broadleaf evergreen plants, draped with vines(lianas), cover 2% of the earth's land surface, contain at least half of the known terrestrial species, niches in distinct layers, decompose quickly, most nutrients are in tree.
16.temperate deciduous forest, dominated by a few species of broadleaf deciduous trees, slow rate of decomposition.
17.evergreen coniferous forest, boreal forest and taiga, dominated by a few species of coniferous evergreen trees, high soil acidity, contain a variety of wildlife.
18.coastal coniferous forests or temperate rain forests, ample rainfall or moisture form dense ocean fogs.
