What does succession mean in ecology?

Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. … The structure of this community becomes more complex as new species arrive on the scene.

What is an example of succession in ecology?

Succession can happen even in mature or climax communities. For example, when a tree falls in a mature forest, sunlight may again be able to reach the forest floor, which would allow new growth to begin. In this case, succession would begin with new smaller plants. Communities are always changing and growing.

What does succession mean in science?

Succession is the change in either species composition, structure, or architecture of vegetation through time. Vegetation has three important aspects that are subject to change. Species composition includes the roster of the species. There can be many or few species in vegetation.

Why is ecological succession?

Ecological succession is important for the growth and development of an ecosystem. It initiates colonization of new areas and recolonization of the areas that had been destroyed due to certain biotic and climatic factors. Thus, the organisms can adapt to the changes and learn to survive in a changing environment.
