Not like a desert, water is not an issue in the tropical rainforest. Still, there may be intense competition, only in this case other sellers is for light and nutrients. the canopy layer of the rainforest.

Having many tall trees forming a multi-layer canopy, not very much light gets to the forest bottom, and competition for light is strong. Sometimes the forest floor may be relatively bare because there is simply not enough light. With this competition to be a backdrop, the profusion of epiphytes and vines from the tropical rainforest makes sense. Rather than grow huge trunks to hold on to their leaves up to the light-weight, epiphytes and vines "cheat" by growing on the top down. Here's how it is effective: A monkey or bird eats the fruit of epiphyte, and scurried or flies completely to another spot, where it defecates. The plant seeds, embedded in a rich pile connected with feces, get caught up on the bark or from the crotch of a tree high up from the canopy where there is more light-weight. In the case of vines, they rapidly send roots because of the ground to get minerals (mineral water is plentiful); epiphytes may grow up against the tree or form a basin because of their leaves. The basin will fill with a number of water and feces from canopy dwelling animals along with the epiphyte can extract minerals from that trapped water. Perhaps no vine exhibits this tactic better than the Strangler Fig (suitable). The seeds germinate in the crown on the canopy and a root slithers because of the forest floor. Making contact, the item immediately begins to send nutrients skyward, along with the fig in the crown responds by means of dropping additional roots down the trunk area. Eventually the roots completely encircle the trunk and to fuse; above in the canopy this fig is shading out the coordinator tree's leaves. The host tree sickens in addition to dies, and eventually decomposes. This actually leaves the strangle fig standing tall, its fused roots forming a hollow trunk as tall for the reason that original tree.

Getting light is solely half the story. Nutrients can be difficult to find as well. The heavy rains dissolve nutrients on the forest soil and carry them absent. The remaining bedrock is slow to give that up minerals, and these are again easily washed away. Plants, therefore, have to visit to extreme lengths to retain the nutrients before there're washed away.

In a temperate high, many of the nutrients are retained from the soil, and as leaves decompose additional nutrients are releases towards soil to be taken up almost at leisure because of the trees. When the forest is slice, the soil remaining is exceptionally loaded and, with care, will sustain agriculture for an extended time. On the other hand, in the warmth of the tropics leaves decompose quickly along with the rain threatens to carry away this nutrients. To stop this, a dense root mat develops in tropical woods, usually this root may is right at first glance, and leaves decompose and release their nutrients on to the roots - the nutrients never enter the mineral soil therefore are not prone to being cleansed away. This effect is particularly pronounced in poorer soils from the tropics. The example to the left is at a volcanic slope in Costa Rica; volcanic soils usually are rich in nutrients so competition for nutrients - and development of any root mat - is not as extreme here the way it is in some other places from the tropics. It should also be mentioned that development of shallow roots is usually a sign of forest maturity outside the tropics likewise; in the United States Beech trees are on the list of trees characteristic of a mature forest and in addition they typically have their roots right on the surface.

Another important aspect of other sellers for nutrients is the role of which fungi play. Not only do fungus help decay the fallen leaves, but quite a few form mycorrhizal associations with plant roots trading nutrients towards plants for sugars in return. These mutualistic associations greatly enhance the ability of forest plants to attain nutrients.the canopy layer of the rainforest
