Question

Why is ecological succession important?

Answer 1

Hint: Ecological succession, it is the process of a gradual change in the species structure of an ecological community over time. The time span can be decades or even it can be millions of years after a mass extinction. Nothing remains the same after ecological succession. The habitats are constantly changing in this process. There are $2$ types of ecological succession.
$1.$ Primary Ecological Succession and $2.$ Secondary Ecological Succession.

Complete Answer:
Ecological succession is the process of change in the species structure of an ecological community over time.
The importance of ecological succession is the growth and development of an ecosystem. It initiates colonization of newly developed areas. And recolonization of the areas that had been destroyed due to certain biotic factors like human interference and climatic factors like flood, bonfire, volcano etc. So that the organisms can adapt to the changes and learn to survive in a changing environment.

Additional Information:
$1.$ Primary Ecological Succession: -
Primary succession is the first type of ecological succession among the two types of ecological succession. It occurs in an environment where a newly formed area is colonized for the first time by a group of species or a community.
$2.$ Secondary Ecological Succession: -
Secondary succession occurs when the severity of destruction is insufficient to abolish all the existing vegetation and soil from a site. Many different kinds of disturbances like human activities, windstorms, flooding, fire etc. can initiate secondary ecological succession.

Note:
In 1885, the term Ecological Succession was given by Ragnar Halt.
When the structure of an ecological system changes on a cycle basis, then the succession is called cyclic succession.
The transitional stage of an ecological succession is called a serial community. A serial community is progressing towards the climax community of an ecological succession.
The fully grown final or the terminal community of an ecological succession is called the climax community.
