Solution
The correct option is A Psammosere
Ecological succession is a steady, gradual change in the composition and structure of biotic communities of an area.
The ultimate purpose of ecological succession is to form an established climax community which is in near equilibrium with the environment.
In an effort to reach this equilibrium, many transitional communities known as seral stages are formed. The entire sequence of communities that successively change in a given area is called sere.
Types of ecological succession based on habitats:
Xerosere: sere originating in dry areas.
Examples: Lithosere (on rocks) and psammosere (on sand).
Hydrosere: sere originating in aquatic environments such as fresh water bodies.
Halosere: sere originating in saline environment.
Hence, psammosere is an ecological succession that started life on sand.
