Soil Profile!
The soil in the Tundra has a unique soil structure, we think of it as permafrost. Permafrost is a layer of soil that stays frozen all year round. Even during the summer the lower layers of soil will remain frozen and biologically inactive, but the upper layers will thaw out. The permafrost in the Tundra forms a barrier keeping reptiles and anphibians from burrowing down into it's soil. Permafrost is said to be one of the main reasons why trees don't grow in the Tundra biome.
How does Succession demonstrate equilibrium/stability in the Tundra?
Succession is the sequence of events that follows a disaster. Succession demonstrates equilibrium/stability in the tundra by representing how oil spills have changed the way soil looks to us and on the enviornment. Also Succession tries to maintain the same enviornment in the tundra biome because succession tries to maintain the amount of animals in the environment and also kills off some organisms because of some disasters.
Primary and Secondary Scuccession!
Primary Succession- The Tundra is made of ice, so that means glaciers. When the earth around the glaciers warmed up the glaciers retreated. They left beind lifeless and looking very rocky, rugged, and plain. It took a very long amount of time for plants like the pioneer plants to start growing on the rocks, and example is lichen. As time past on, rocks broken down by the lichens mixed with decaying lichens and formed the first soil. Wind had also blew around dust, which congregated in small cracks in rocks, which is where moss and small plants started to grow. Moss obtains water by absorbing moisture in the air. After this happens more moss and more soil starts to form. Soil is made becasuse decaying rock bits and moss mixtures come together to form the soil.When soil is formed grass starts to grow, so as a result, grass begins to grow in the area. As soil becomes more plentiful,or better too use, and easier too use for growth more and more plants begin to grow. These stages of soil and plant sophistication are a representation of primary succession. This is an example of primary succession because it demonstrateshow plants and animals develop in biomes where there is no topsoil. With the soil just forming it is showing how the plants and animals will evolve from the new life the earth is giving them.
Secondary Succession-When a natural disaster, like a fire or a hurricane, reduces an already established ecosystem, which means it messes with the ecosystem after it's already put together and formed a place for things and animals to grow and live. Because the soil is already present during this it's secondary succession. This happens because the soil remains and succession follows after it occurs. Secondary succession is faster than primary succession because the soil is already there. In the tundra this could occur after a fire or a mudslide
How Are the Two Different?
Primary succession is when plant and animals develope in biomes where there is no topsoil.
Secondary succession is how new organisms are developed and the old ones are replaced by the new ones.
