I have somewhat of a understanding of this scenario. However, I am looking for a second opinion.I would like understanding the following:
This story begins about 7,000 years ago, with a small creek running through a forest. Beavers dam the creek to create a pond in which they can build a lodge. the beaver dam prevents the natural flow of the stream, and water begins to flood the valley. The water spreads throughout the forest, filling the soil around the roots. The first plant to inhabit the pond is sedge grass. The extension of the sedge roots into the open water forms the beginning of a bog mat on the water's surface. As the sedge spreads out across the pond, sphagnum moss and leather leaves grow behind it. Detritus produced by the mat sinks to the bottom, Beginning the process whose end product is peat the partially carbonized remains of plants, used by humans as fertilizer and fuels. Trees begin to grow where the bog mat is firmer and more established. The accumulation of peat begins to raise the level of the bottom of the pond. As the bog mat grows out over the pond, it provides firm ground on which new trees can grow. The mat grows over most of the pond's surface, and the pond fills in with peat. The only water remaining is a marrow, clear flowing stream. The sphagnum moss, leather leaf and other hardy bogs plants crowd out the sedge grass. the trees continue to grow, and the bog develops into a forest. I believe this is what is called "secondary" succession?© BrainMass Inc. brainmass.com September 20, 2018, 5:08 pm ad1c9bdddf - https://brainmass.com/biology/ecology/succsession-flooded-forest-307821
So generally speaking there are two kinds of succession: Primary and Secondary. So for your purposed let us just focus on secondary succession. A common definition would be something along the lines of: Secondary succession refers to the regrowth of a habitat in the area where a disruptive event has occurred ...
The solution first reviews the principles of primary and secondary succession and then illustrates how the given scenario fits in.
