Is repeated freezing and thawing of water that cracks rocks
No, it would be chemical weathering.
rain forest
Weathering leaves more pieces behind, which eventually lets the rock stick the pieces back to itself, giving erosion a bigger job since the rock keeps growing.
leaves
Because leaves from an upper canopy high above the forest floor. Also , because trees that grow in the raim forest include species of myrtle,laurel ,palm , rosewood ,mahogany ,and ceder , to name just a few.
Leaf
Yes, worms eat decaying leaves.
Millipedes-they eat decaying leaves, and so do other bugs.
The decaying leaves are returning nutrient to the soil. The undecayed parts help to improve the soil.
When leaves and other organic matter lie on the forest floor, they begin to decompose. This layer of decomposing organic material is called litter.
Yes
Deciduous trees start to drop their leaves in the autumn leaving the forest with a layer of leaves. The leaves decay and eventually become part of the fertile floor of the forest. The decaying process happens in many ways. Animals and insects ingest (eat) the leaves converting it to fecal material adding fertilizer to the ground. Worms chew through the leaves and fungus (mold) and bacteria also help consume the ground cover accomplishing the same thing.
Forests survive naturally because they have their own cycle. Decaying plants and leaves and foods (berries, dead animal meats, ect.) on the forest floor act as fertilizer ot promote the growth of other plants.
Bamboo has adappted well to its environment that it lives in, bamboo has large leaves that kepps away some of the water and also bamboo lives of the decaying matter of the forest floor.
chemical
Millipedes live in decaying leaves and plants.
As we know Millipede's thrives by eating decaying leaves and grasses. Hence a number of folded-up leaves on decaying materials is enough to make home for Millipede... :)
organic matter and humus are related because they are darker in a way. and many leaves that fall from forest trees every autumn help form humus. the decaying leaves and plentiful rainfall form thick fertile soil.
