The number of species that become extinct due to habitat destruction is greatest in ....... ecosystems with ....... many species.

Options

A. temperate, migratory
B. tropical, endemic
C. temperate, keystone
D. tropical, migratory

Answer

To answer the question regarding the number of species that become extinct due to habitat destruction, we need to analyze the ecosystems and the types of species involved.

### Step-by-Step Solution:

1. **Identify the Ecosystem**:
- The question asks about the ecosystem where the number of species that become extinct due to habitat destruction is greatest.
- Research indicates that tropical ecosystems are the most affected by habitat destruction. This is primarily due to high rates of deforestation and land-use changes in these regions.

2. **Understand Species Diversity**:
- In tropical ecosystems, there is a high level of biodiversity, meaning there are many different species living in these areas.
- The greater the number of species, the higher the likelihood that some will become extinct if their habitat is destroyed.

3. **Focus on Endemic Species**:
- Many species found in tropical ecosystems are endemic, meaning they are unique to that specific geographic area and cannot be found elsewhere.
- Endemic species are particularly vulnerable to extinction because if their habitat is destroyed, they have no alternative locations to migrate to.

4. **Conclusion**:
- Based on the above analysis, the number of species that become extinct due to habitat destruction is greatest in **tropical ecosystems** with **endemic species**.

### Final Answer:
The number of species that become extinct due to habitat destruction is greatest in **tropical ecosystems** with **endemic species**.
