Question

Culmination of succession at a stage other than natural climax is called?
A. Deflected sere
B. Disclimax
C. Plagioclimax
D. Both B and C

Answer 1

Succession has been the most abrupt change in the community pattern of the forms of life. Change is the only constant in every species. Wherever there is life there is evolution due to the change in the physical and chemical environment of that area to adapt itself to the environment.

Complete answer:
An ecological community is an organization in which there is stability in the populations of animals and plants and they exist in balance with each other and with the environment. A climax community is the last stage of succession that remains unchanged until destroyed by a fire or human interference.
Disclimax is a community that replaces the natural climax community due to interruptions created by human activities and consists of animals and plants that are new to that region.
So, this can be considered as a stage of succession other than a natural climax.
Plagioclimax is the stage when succession does not reach the climax and is stopped in the mile due to certain interruptions such as the destruction of vegetables.
Therefore this can also be considered as a stage of succession other than a natural climax.
Hence, Disclimax and Plagioclimax are the culmination of succession apart from natural climax.
So, the correct answer is “Option d”.

Additional Information:
Ecological succession is divided into three fundamental phases: Primary, Secondary, and a climax state.
Primary succession occurs when organisms capture and start living in an area that has no life, such as barren land. Examples of this succession is algae and fungi colonizing a barren land or a rock.
Secondary succession occurs when an already established community is replaced with a different set of plants and animals.
Intermediate stages are also a part of the ecosystem succession which act as joining bridges between the endpoints of secondary succession and starting points of the climax community.
A climax community is the most stable of all the communities and can vary in a particular region especially when there is a high difference in terrain.

Note:
Climax community is the final development a species can undergo to stay alive or prevailing in a particular area. Also, it is the most stable community of all the other successions because it has been developed over time. It takes around a century to get a community which by all means can prevail in the changes of the climatic conditions of that area and adapt to it. Therefore, it is the community that is completely adaptive to the environment.
