Question

Clements is mainly responsible for the following theory.

• A. Poly climax
• B. Mono climax
• C. Mosiac
• D. Multiclimax

Hint:

Mnemonic:
- Clements = Monoclimax (one climate, one climax).
- Tansley = Polyclimax (multiple climax types controlled by soil, fire, or topography).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Ecological succession is the process by which the structure of a biological community evolves over time.
The fil, stable stage of succession is called the climax community.

Step 2: Detailed Explation:
The Monoclimax Theory of ecological succession was proposed by F.E. Clements in 1916.
This theory asserts that within a given climatic region, there is only one true climax community toward which all successiol pathways (regardless of initial soil or moisture conditions) will eventually converge.
Clements argued that climate is the sole determining factor of the climax community, which is why this stable endpoint is called the "climatic climax".
Other successiol states (such as those arrested by soil conditions or fire) are considered temporary sub-climaxes that will eventually transition to the climatic climax over geological time.
In contrast, Tansley proposed the Polyclimax Theory, which argues that multiple stable climax communities can coexist in a single region, determined by soil (edaphic), topographic, or fire factors.

Step 3: Fil Answer
F.E. Clements is responsible for the Monoclimax Theory of ecological succession.
