Many of Indonesia's forests include in Tropical Rain Forest is a complex community whose framework is provided by trees of many sizes. Forest canopy is used as a general one to describe the total plant community above the ground. Within the canopy the microclimate differs from that. outside; there is less light, humidity is higher, and temperature is lower. Many of the smaller trees grow in the shade of the larger ones in the microclimate that these produce. Upon the framework of the tree and within the microclimate of the canopy grow a range of other kinds of plants: climbers, epiphytes, strangling, plants parasites, and saprophytes. The trees and most of the other plants are rooted in the soil and draw nutrients and water from it. Their fallen leaves, twigs, branches, and other parts provide ; food for a host of invertebrate animals, amongst which termites are often important, and for fungi and bacteria. Nutrients are returned to the soil via decay of fallen parts and by leaching from the leaves by rain-water. It is a feature of tropical rain forest that most of the total nutrient store is in the vegetation; relatively little is held in the soil.
