Question

Which one of the following statements is true about endemic species?

• A. They are found exclusively in a specific habitat.
• B. Endemic species can never become endangered.
• C. They are found only in zoos and botanical gardens.
• D. They are not affected by the destruction of their habitat.

Answer 1

The correct option is A

They are found exclusively in a specific habitat.

The correct option is A.
Explanation for the correct option:

1. In biology, the term "endemism" refers to the geographic distribution of a taxon that is only present naturally in a narrow geographic area.
2. As a result, endemic species are those that only exist in a particular region, such as a mountain range, lake, island, etc.
3. They can only be discovered in a certain habitat.
4. A species that is confined to a certain geographical area is said to be endemic.
5. The species can be microbes, fungi, animals, plants, or even zooplankton.
6. The area may be modest or substantial.
7. As previously said, endemic species are ones that can only be found in a particular area or locality and nowhere else on Earth.
8. Endangered species are more susceptible to extinction because they are specific to a certain area of the world.
9. Therefore, specific measures may be needed to preserve them.

Explanation for the incorrect options:
Statement (B):

1. Biological, physical, and environmental factors all affect endemic species.
2. They have the ability to breed with one another.
3. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
4. Natural occurrences may result in habitat loss.

Statement (C):

1. Although the indigenous species can be seen in captivity, their survival is not very long in those circumstances.
2. As a result, endemic species are those that only exist in a particular region, such as a mountain range, lake, island, etc.

Statement (D):

The native habitat of endemic species may be impacted by habitat destruction, rising human population, and the introduction of new species by forcing them to adapt to new conditions and putting their survival in jeopardy.

Final answer: The correct statement is A - They are found exclusively in a specific habitat.
