Succession is natural, gradual changes in the type of species that lives in an area. Whether it be primary or secondary succession occurring in the ecosystem. Primary takes longer to reach the climax community because of the bare rocks that later on forms into soil by the pioneer species over a period of multiple years. When the pioneer species die and decompose, they leave a very small amount of organic material for later on use of becoming soiled for instance lichens or moss. The organic material being added to the soil gives the soil more nutrients, allowing more diverse but little, simple plants. Once again, when these simple plants die they give more nutrients to the soil, allowing complex plants like small bushes and trees to grow. When it reaches this stage, small organisms start to move in insects, small birds, and mammals.
Secondary succession is the reestablishment of a damaged ecosystem in an area where the soil was left intact. Since some nutrients are already present in the soil in this environment, it can sustain plants that are more elaborate early than in primary succession. In years to come, some simple plants start to reproduce like grasses, weeds that eventually start to take over. The whole process that occurred during primary succession will follow, but where it took hundreds of years to reach climax …show more content…
When lichens die after breaking down the bare rock into soil, small annual plants start to grow alongside lichens. Grasses and perennials herbs come and go where later on the intermediate species come into play. Such organisms like grasses, shrubs, and shade intolerant trees (such as pines). When breaking down into nutrients for the soil it allows more varied and more complex plants. When it reaches this stage, it is considered to be the climax community. When comparing the pioneer species to the climax community you would see such things
