Assertion : Threatened species should be given preference over others in the conservation programme.
Reason : All the life supporting system (air, water and land) should be conserved .

Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the Reason is not the correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that threatened species should be prioritized in conservation programs. This is based on the idea that these species, which are at risk of extinction, require immediate attention to prevent their decline.

2. **Identifying Threatened Species**: Threatened species include those categorized as endangered, vulnerable, or lower risk. These species can often be saved with relatively less effort compared to critically endangered species.

3. **Conservation Methods**: Conservation can be done through in-situ (on-site) or ex-situ (off-site) methods. Programs are designed to protect these species in their natural habitats or in controlled environments.

4. **Statistics on Threatened Species**: The video mentions that approximately 37% of mammal species, 38% of bird species, 21% of reptiles, 16% of amphibians, and 14% of angiosperms are considered lower risk. This indicates that with focused conservation efforts, these species can thrive again.

5. **Understanding the Reason**: The reason states that all life-supporting systems (air, water, and land) must be conserved. This is crucial because the survival of species is directly linked to the health of their ecosystems.

6. **Link Between Assertion and Reason**: While both the assertion and reason are true, the reason does not directly support the assertion. The assertion focuses on prioritizing threatened species, while the reason discusses the broader context of ecosystem conservation.

7. **Conclusion**: Therefore, both statements are true, but the reason is not the correct justification for the assertion. The correct answer is that the assertion is true, and the reason is true but does not support the assertion.

**Final Answer**: The assertion is true, and the reason is true but does not support the assertion.
