How does the change of biogeocenoses proceed?

Ecosystem changes can occur quickly, before the eyes of one generation of people: overgrowth of small water bodies, restoration of forests after a fire, restoration of forest ecosystems after their plowing. In most cases, the change and development of biogeocenoses under the influence of living organisms themselves last thousands of years. For example, at first grasses, willows, burrowing spiders, grasshoppers, and burrowing wasps settle on the bare sand dunes. Pine appears, then deciduous trees, fauna becomes more diverse. The first settlers are joined by ants, filly, beetles. Development, which began on a dry and barren territory, ends with the formation of a stable ecosystem – a moist deciduous forest with a powerful, humus-rich soil, with earthworms and mollusks, and a diverse fauna.
