Which one of the following is not a correct match of the term and its description?

Options

A. Ecology-Environmental biology
B. Biosphere-The inhabited part of the earth
C. Biome-A major life zone characterized by the dominant plant life present
D. Ecological level-Organisms occupying different equivalents niches in same geographical area

Answer

To determine which term and its description are not correctly matched, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Identify the Terms and Descriptions**:
We have several terms related to ecology and their descriptions. We need to evaluate each one to see if they are correctly matched.

2. **Evaluate the First Option - Ecology**:
- **Term**: Ecology
- **Description**: The study of organisms and their interactions with the environment.
- **Analysis**: This description is correct. Ecology indeed focuses on how organisms interact with each other and their environment.

3. **Evaluate the Second Option - Biosphere**:
- **Term**: Biosphere
- **Description**: The stratum of Earth that is inhabited.
- **Analysis**: This description is also correct. The biosphere encompasses all regions of Earth where life exists.

4. **Evaluate the Third Option - Biome**:
- **Term**: Biome
- **Description**: A major life zone characterized by the dominant plant life present.
- **Analysis**: This description is accurate. Biomes are defined by their climate, soil, and the types of plants and animals that inhabit them.

5. **Evaluate the Fourth Option - Ecological Level**:
- **Term**: Ecological Level
- **Description**: Includes population, community, and ecosystem.
- **Analysis**: This description is partially correct. However, the term "ecological equivalent" refers to organisms that occupy similar niches in different geographical areas, which is not the same as ecological levels.

6. **Conclusion**:
Based on the analysis, the incorrect match is the description associated with "Ecological Level." Therefore, the answer to the question is **Option D**.

### Final Answer:
The term that is not correctly matched with its description is **Option D**.
