Question

Stratification is useful in

• A. Better use of resources
• B. Accommodation of larger number of species
• C. Modification of environment
• D. All of the above

Answer 1

The correct option is D All of the above

• Stratification in the field of ecology is the vertical distribution of different species occupying different levels in an ecosystem. For example, in a forest ecosystem, trees occupy the topmost layer of the forest, shrubs occupy the second top layer while herbs and grasses occupy the bottom-most layer, as shown in the above diagram.
• Stratification is useful for the better use of resources by reducing competition, accommodation of larger number of species and modification of the environment.
