Answer

To solve the question "Habitat together with functions of a species constitute is," we will analyze the options provided and determine which one correctly defines the relationship between habitat and the functions of a species.

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question is asking for a term that encompasses both the habitat of a species and its functional role within that habitat.

2. **Analyzing the Options**:
- **Topography**: This refers to the arrangement of the natural and artificial physical features of an area. It does not encompass the functions of a species.
- **Trophic Level**: This term refers to the position an organism occupies in a food chain. While it relates to feeding relationships, it does not cover the habitat aspect.
- **Boundary**: This term generally refers to a dividing line or limit. It does not relate to the habitat and function of a species.
- **Ecological Niche**: This term refers to the role and position a species has in its environment, including its habitat, resource use, and interactions with other species.

3. **Identifying the Correct Answer**:
- The correct answer is **Ecological Niche**. This term effectively combines both the habitat (where a species lives) and the functions (how it interacts with other organisms and its environment).

4. **Conclusion**:
- Therefore, the answer to the question is **Ecological Niche**.

### Final Answer:
The habitat together with functions of a species constitutes an **Ecological Niche**.
