According to the Clements succession theory, which stage controls the development of a community?
A
nudation
B
competition
C
ecesis
D
reaction
Explanation: 

Detailed explanation-1: -According to the Clements succession theory, which stage controls the development of a community? Recognized by climax communities with multiple vegetation types. The entire environment determines the composition, structure, and the balance of the climax community.

Detailed explanation-2: -The final stage of succession is called the climax or climax community (Clements, 1936; Shimwell 1971). It is the final or stable community in a successional series. It is self-perpetuating and in equilibrium with the physical and biotic environment.

Detailed explanation-3: -The 5 stages of succession are Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization. At the same location, a succession of biotic communities naturally emerge one after another until the Climax stage is reached. In their early stages, biotic communities develop slowly.

Detailed explanation-4: -Clementsian succession is the idea that vegetation in communities changes over time through successive stages by allogenic and autogenic processes until a climax stage is reached. Although the idea is often portrayed in textbooks, it is not widely held by ecologists.
