Vertical distribution of different species occupying different levels in dense vegetation is called

Options

A. stratification
B. species compositon
C. standing crop
D. trophic structure.

Explanation

To solve the question regarding the vertical distribution of different species occupying different levels in dense vegetation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the vertical distribution of various species in dense vegetation.

2. **Identifying Key Terms**: The key terms in the question are "vertical distribution," "different species," and "dense vegetation." This indicates that we are looking for a concept that relates to how species are organized in layers or levels within a habitat.

3. **Exploring the Options**: The options provided are:
- A) Stratification
- B) Species composition
- C) Standing crop
- D) Trophic structure

4. **Analyzing Each Option**:
- **Stratification**: This term refers to the layering of different species in an ecosystem, particularly in dense vegetation like forests. It indicates how species occupy different vertical levels.
- **Species Composition**: This refers to the types and numbers of species present in a community, but does not specifically address vertical distribution.
- **Standing Crop**: This term refers to the total biomass of living organisms in a given area at a specific time, not their vertical arrangement.
- **Trophic Structure**: This refers to the feeding relationships and energy flow within an ecosystem, which does not specifically address vertical distribution.

5. **Selecting the Correct Answer**: Based on the analysis, the correct answer is **A) Stratification**. This term accurately describes the vertical distribution of different species in dense vegetation.

### Final Answer:
The vertical distribution of different species occupying different levels in dense vegetation is called **Stratification**.
