Ecological Succession
Ecological succession is the process by which a community of organisms gradually and predictably changes over time in a given area. It involves the replacement of one community by another, leading to a more complex and stable ecosystem. There are two types of ecological succession: primary succession and secondary succession.
Statement 1: The gradual and fairly predictable change in the species composition of a given area is called ecological succession.
This statement is correct. Ecological succession refers to the gradual and predictable changes in the species composition of an area over time. It occurs as a result of the interactions between the biotic (living) and abiotic (non-living) components of the environment.
Statement 2: The entire sequence of communities that successively change in a given area are called seres.
This statement is incorrect. The correct term for the sequence of communities that successively change in a given area is "seral stages" or "sere(s)". A sere refers to a particular stage in the process of ecological succession. It represents a distinct community of organisms that are adapted to the specific environmental conditions at that stage.
Statement 3: Primary succession begins in areas where natural biotic communities have been destroyed.
This statement is correct. Primary succession occurs in areas where there is no pre-existing biotic community or where the existing community has been completely destroyed, such as on bare rocks, newly formed volcanic islands, or after a glacier retreat. In such areas, pioneer species, such as lichens and mosses, colonize the barren environment and gradually modify it, creating conditions suitable for the establishment of more complex communities.
Conclusion
In conclusion, statement 1 and statement 3 are correct. Ecological succession refers to the gradual and predictable changes in the species composition of an area, while primary succession occurs in areas where natural biotic communities have been destroyed. However, statement 2 is incorrect. The correct term for the sequence of communities that successively change in a given area is "seral stages" or "sere(s)".
