What is stratification in an ecosystem ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Stratification**: Stratification in an ecosystem refers to the division or layering of different components within that ecosystem. It is derived from the term "strata," which means layers or levels.

2. **Vertical Division**: In the context of ecosystems, stratification specifically involves the vertical sectioning of the ecosystem. This means that the ecosystem is organized into distinct layers that can be observed from the ground up.

3. **Layers of Vegetation**: The stratification often pertains to the layering of vegetation. Different types of plants and trees occupy different vertical levels within an ecosystem.
