Vertical distribution of different species occupying different levels in a biotic community is known as:
- zonation
- pyramid
- divergence
stratification
The Correct Option is D
Solution and Explanation
Stratification is the vertical distribution of different species occupying different levels in a biotic community. It is formation of vertical layers where vegetation is dense, i.e. 5-7 strata (layer) in tropical rain forests with emergent tall trees, canopy trees, shrub layer below tree layer, bottom layer of herbs and grass at ground level. Zonation is the horizontal categorization of biomass into zones based on their distribution or arrangement in habitat as determined by environmental factors, e.g. altitude, latitude, temperature, biotic factors, etc.
So, the correct option is (D): stratification.

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.
