Options

A. An endemic species that is found nowhere else in the world
B. A species that is in a sink habitat
C. A species that is in danger of extinction in all or a large part of its range
D. 1A species that is likely to become endangered

Answer

To answer the question regarding the definition of a threatened species according to the Endangered Species Act, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the definition of a "threatened species" as per the Endangered Species Act.

2. **Reviewing the Options**: We have four options to evaluate:
- **Option A**: An endemic species found nowhere else in the world.
- **Option B**: A species that is in a sink habitat.
- **Option C**: A species that is in danger of extinction in a large part of its range.
- **Option D**: A species that is likely to become endangered.

3. **Evaluating Option A**:
- Endemic species are unique to specific locations and do not define a threatened species.
- **Conclusion**: Option A is incorrect.

4. **Evaluating Option B**:
- A sink habitat refers to an area where populations cannot sustain themselves if separated from their original source. This does not specifically define a threatened species.
- **Conclusion**: Option B is incorrect.

5. **Evaluating Option C**:
- This option suggests that a threatened species is one that is in danger of extinction across a large part of its range. However, this definition aligns more closely with "endangered species" rather than "threatened species."
- **Conclusion**: Option C is incorrect.

6. **Evaluating Option D**:
- This option states that a threatened species is one that is likely to become endangered. This aligns with the definition of a threatened species as per the Endangered Species Act, which indicates that these species are at risk but not yet in immediate danger of extinction.
- **Conclusion**: Option D is correct.

7. **Final Answer**: According to the Endangered Species Act, a threatened species is defined as a species that is likely to become endangered in the foreseeable future.
