The value of Z , the slope of the line ( regression coefficient ) is …..... for mammals in the tropical forest of different continents.

Options

A. 0.6
B. 0.8
C. 1.15
D. 1.21

Answer

To determine the value of Z, the slope of the regression coefficient for mammals in tropical forests across different continents, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Z**:
- Z represents the slope of the line in the species-area relationship. This relationship describes how the number of species (in this case, mammals) increases with the area of habitat available.

2. **Identifying the Specific Value for Mammals**:
- According to surveys and studies on mammals in tropical forests, the specific value of Z for mammals has been determined.

3. **Finding the Value of Z**:
- The video transcript mentions that the value of Z for mammals in tropical forests is 1.15. This value indicates a positive correlation between the area of the habitat and the number of mammal species present.

4. **Understanding the Context of Frugivorous Species**:
- The value of 1.15 is particularly noted in relation to frugivorous mammals, such as fruit-eating bats, which are significant members of the mammalian community in tropical forests.

5. **Conclusion**:
- Therefore, the value of Z, the slope of the regression coefficient for mammals in tropical forests of different continents, is 1.15.

### Final Answer:
The value of Z is 1.15 for mammals in the tropical forest of different continents.
