Imagine slicing a cross-forest. Forest seemed to consist of three parts, the parts above ground, above ground parts, and the underground.
If we trace the above ground parts of the forest, you will see their canopies (crown) of trees, stems natural wood, and lower plants such as shrubs and bushes. In natural forests, canopy trees are usually visible layers because there are different types of trees growing at different times.
At the soil surface, it appears a variety of shrubs, grasses, and litter. Litter is also called 'forest floor', though more like a rug. The litters were avalanches all stems, branches, leaves, twigs, flowers, and fruit. Litter has an important role as a source of humus, the fertile top soil layer. Litter also become the home of insects and various other micro-organisms. Interestingly, the residents actually consuming litter, house them; destroy it with the help of water and air temperature so that the soil humus is formed.
Beneath the forest floor, we can see the roots of all plants, both large and small, in various forms. Up to a certain depth, we can also find a place to live several different animals, like insects, snakes, rabbits and other rodents.
