Soil ecology By Kacey Tana

Rock layers  Ground layer: plants grow and animals live here. A thick cover of plants can keep the soil cool and from dying out.  Topsoil: plants grow and animals live on the top of the soil. It is sometimes called the organic layer.  Subsoil: it is a mix of mineral particles and some humus near the top.  Weathered plant material: no organic material down here. Out of reach of dead and alive organisms. All rock material.  Bedrock: entirely made of solid rock. It waits on the bottom until erosion or an earthquake exposes it to the surface.

organisms  Scientists work hard to find and identify soil wildlife. The smallest organisms are probably the most important to soil.  Each one of these organisms have thousands of cousins related to them.  These organisms include amoeba, bacteria, beetle mite, eastern mole, nemotode, night crawler, and rock fungus.

Soil safari A toxic spill can easily go into the ground and make its way to an underground water system that can kill all organic life on the surface. A toxic spill can easily go into the ground and make its way to an underground water system that can kill all organic life on the surface.

Recipe for soil First, select a large quantity of bedrock. You can start with a fresh lava flow, a solid granite dome, or some limestone. First, select a large quantity of bedrock.

Use a glacier to grind off big boulders and fine sediment. Physical weathering: Next, break some of the parent material into pieces. Use a glacier to grind off big boulders and fine sediment. Chemical weathering: Now change some of the parent material and the mineral particles into other kinds of minerals. Run water over limestone to dissolve the limestone and make the water more acidic.

Biological actions: Finally, start with some early colonizers like lichens. Then throw in a stock made of microscopic decomposers.
