As you can this is an example of succession and would happen very gradually over time.
In my biome there are 4 seasons and each season is gradually replaced by the next as new organisms come out and interact. For example bears live and interact with the outdoors and other organisms in the spring and summer, but during fall they prepare for winter and then go into hybernation. Also the change of the seasons is another example. The seasons don't go 90 degree summers to 20 degree winter's, everything changes gradually. If the season's did change like this the environment would not be able to adapt to the surroundings and things would go into shock. This is ecological succession, when an existing community is gradually replaced by another community.
Because the seasons change gradually and allow the environment and organisms to adapt this allows dynamic equilibrium or stablity in my biome. The gradual change allows time to prepare and adapt to the surroundings. If the changing of seasons would happen all of a sudden species could die off without the time to adapt and prepare and then when the season changes back the species may not come back. When the gradual change of seasons happens, species can prepare and protect themselves more than they could and this increases their chance of coming back next season instead of dying off immediately and erasing the species.
For example if the bears didn't have time to prepare for hybernation and find shelter, winter could come and the bears could die off. so when spring comes and the bears are supposed to come out of hybernation all of them would be dead and this would set the biome off balance.
Secondary succession is when a disturbance affects the community without completely destroying it, meaning there is remnants of a previous community. The temperate deciduous forest has secondary succession as with each season not everything dies off or changes right away. For example the funky weather in Indiana this year has caused it to not really have a winter like it normally does. Because of this the pollen and bugs that normally die off during the winter didn't an therefore this is an excess of pollen and mosquitoes that normally come out in the summer are coming out sooner than normally. Also the flowers and plants that started to die in the fall didn't completely die off in winter this year, as it was not cold enough, so there were enough remnants left for the flowers and plants to start growing earlier than normal. Now given this doesn't happen normally secondary succession also happens from season to season.
There are 4 different types of soil that can be found in my biome and they are Alfisols, Ultisols, Rocky Soils, and Sandy Soils.Alfisols is the most common type and is also known as a brown forest soil. It contains a top layer, primarily dead leaves, and a subsoil, which has a high content of clay. They get their color from humus. Humus is decayed leaves and other organic matter. Alfisols in this biome is less acidic and contain less iron and aluminum. Ultisols is also common but more in the southern hemisphere.It is clay-rich soil that is much older than alfisol counterparts and has undergone much higher levels of leaching and weathering. It provides poor aeration and lacks nutrients and is mostly brown in color and can contain streaks of red or yellow.Rocky Soils is more common on hillsides and rocky outcrops because they are dry and infertile due to the nonporous mineral particles. Rocky soils usually occur on slopes because of water draining away quickly and this causes only small trees, like hickories, to grow. The soil's alkalinity is elevated when limestone is present. Sandy Soils occur along coastlines of this biome. Sandy soils consist of sand mixed with small amounts of dirt and is very low in nutrients. It is poor in retaining water, but is still able to grow a few trees, like pitch pines, but they are often stunted.
