Almost all tree species use what are calledmycorrhizae (meaning fungus-roots) to obtain some of their nutrients. Parasitic symbioses take many forms, from endoparasites that live within the host's body to ectoparasites that live on its surface. The tadpole feeds on the developing insect larvae of the catchment. Japanese cedar and Japanese stone oak are the dominant tree species, while moso bamboo and a wide diversity of mosses and lichens comprise the understory. On the western windward sides of the mountain slopes, the higher air moisture due to facing the ocean favors the growth of western hemlocks and silver firs (Abies amabilis). For example, at a site near Manaus, Brazil, rain brought three kilograms of phosphorus, two kilograms of iron, and ten kilograms of nitrogen per hectare annually. Throughout Olympic National Park, mosses and lichens play an important role in many different ecosystems.

The only way out is through a tube. The global distribution of the tropical rainforest can be broken into four continental regions, realms or biomes: the Ethiopian or Afrotropical rainforest, theAustralasianor Australian rainforest, the Oriental or Indomalayan/Asian rainforest, and the Central and South American Neotropical. These communities serve as a transition between the flourishing montane forests below and the barren alpine biome above, with trees getting shorter and shorter as the elevation rises and climate conditions become too insurmountable for survival.
