The Correct Option is A

Solution and Explanation

Biotic or ecological succession is the natural development of a series of biotic communities at the same site, one after the other till a climax community develops which does not change further because it is in perfect harmony with the environment of the area. The change is orderly and sequential. The first biotic community which develops in a bare area is called pioneer community. It has very little diversity. Climax community is a stable, self perpetuating and final biotic community. It develops at the end of biotic succession and is in complete equilibrium with the prevailing environment. The establishment of climax stage is called stabilisation.

Concepts Used:

Ecosystem

An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.

Structure of the Ecosystem:

The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment. 

There are two main components of the structure of an ecosystem, namely: 

  • Biotic Components
  • Abiotic Components

The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
