Define stratification.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Concept**: Stratification refers to the organization or arrangement of different layers within a particular area. This can apply to various contexts, including ecology, geology, and social sciences.

2. **Defining Stratification in Ecology**: In the context of ecology, stratification specifically refers to the vertical arrangement of organisms within an ecosystem. This means that different species or groups of organisms are found at different heights or levels in a given area.

3. **Layers in Stratification**: These layers can include various levels such as the ground layer, understory, canopy, and sometimes even higher levels depending on the ecosystem (like in forests). Each layer can support different types of organisms adapted to those specific conditions.
