Vertical distribution of different species occupying different levels ...
Stratification is the occurrence of vertical zonation in the ecosystem & indicates the presence of favorable environmental conditions, for e.g., trees occupy top vertical strata or layer of a forest, shrubs the second. Herbs & grasses occupy the bottom layers. It is absent or poor where environmental conditions are unfavorable, e.g., desert ecosystems have very few trees & shrubs.

Stratification in a Biotic Community
Vertical distribution of different species occupying different levels in a biotic community is known as stratification. This organization helps maintain balance and diversity within the ecosystem.
Importance of Stratification
- **Resource Utilization**: Each species occupies a specific level based on its adaptation and resource requirements, minimizing competition for resources.
- **Biodiversity**: Different levels of the community support a variety of species, contributing to overall biodiversity.
- **Energy Flow**: Stratification allows for efficient energy flow through the community, as each level plays a specific role in the food chain.
Examples of Stratification
- **Canopy**: In a forest ecosystem, tall trees make up the canopy layer, providing habitat for birds, insects, and other organisms.
- **Understory**: Beneath the canopy, shrubs and smaller trees form the understory layer, supporting a different set of species.
- **Forest Floor**: The forest floor is inhabited by decomposers, fungi, and small mammals that play a crucial role in nutrient recycling.
Conclusion
Stratification in a biotic community is essential for maintaining ecological balance and supporting diverse species. Understanding the vertical distribution of species helps in conservation efforts and ecosystem management.
