Assertion (A) : Many species like Stellers sea cow, passenger pigeon, etc., became extinct due to over exploitation.
Reason(R) : Over exploitation is a major cause of biodiversity loss.
The correct answer is option 'B', which states that both the assertion (A) and the reason (R) are true, but the reason is not the correct explanation of the assertion. Let's understand why.
Explanation:
Overexploitation and Extinction:
- Overexploitation refers to the excessive use or extraction of natural resources beyond their sustainable limits.
- Many species have become extinct due to over exploitation by humans. Some examples include Stellers sea cow and passenger pigeon.
- Stellers sea cow, a large marine mammal, was hunted extensively for its meat and hide, leading to its extinction within 27 years of its discovery.
- Passenger pigeon, once one of the most abundant bird species in North America, suffered from overhunting for food and feathers, resulting in its complete extinction by the early 20th century.
Biodiversity Loss and Overexploitation:
- Biodiversity loss refers to the reduction in the variety and abundance of different species in a particular habitat or ecosystem.
- Overexploitation is one of the major causes of biodiversity loss.
- When a species is overexploited, its population declines rapidly, and if the decline continues, it may lead to the extinction of that species.
- The loss of a species impacts the overall biodiversity of an ecosystem, as every species plays a crucial role in maintaining the balance and functioning of the ecosystem.
Relation between the Assertion and Reason:
- The assertion states that many species became extinct due to over exploitation, which is true as mentioned in the examples of Stellers sea cow and passenger pigeon.
- The reason states that over exploitation is a major cause of biodiversity loss, which is also true.
- However, the reason alone cannot explain why many species became extinct due to over exploitation. Other factors like habitat destruction, pollution, climate change, etc., also contribute to biodiversity loss and species extinction.
- Therefore, while both the assertion and the reason are true, the reason does not provide the complete explanation for the assertion.
Conclusion:
In conclusion, over exploitation is indeed a major cause of biodiversity loss, leading to the extinction of many species. However, it is important to consider other factors as well to fully understand the reasons behind species extinction.
Reason(R) : Over exploitation is a major cause of biodiversity loss.
The correct answer is option 'B', which states that both the assertion (A) and the reason (R) are true, but the reason is not the correct explanation of the assertion. Let's understand why.
