Show Hint
If the protection is built around its existing home, it is In-situ.
- A, B and E only
- B, D and E only
- C, D and E only
- A, B and C only
The Correct Option is A
Solution and Explanation
The question differentiates between two main strategies for biodiversity conservation: In-situ (on-site, in the natural habitat) and Ex-situ (off-site, away from the natural habitat).
Step 2: Detailed Explanation:
• Ex-situ Conservation: This involves moving endangered species or their genetic material to a safe, human-managed environment.
- Gene Banks (A): Store seeds, pollen, or sperm in controlled cold conditions.
- Tissue Culture Repositories (B): Maintain living plant tissues (meristems, etc.) in a sterile, in-vitro environment.
- Botanical Gardens (E): Collections of living plants grown for research and public display.
- Other examples include Zoos and Aquaria.
• In-situ Conservation: This protects the species by protecting its entire ecosystem.
- National Parks (C): Strictly protected areas for wildlife.
- Biosphere Reserves (D): Large areas aimed at sustainable development and habitat preservation.
- Other examples include Wildlife Sanctuaries and Sacred Groves.
Final Answer:
Items A, B, and E are off-site (Ex-situ), while C and D are on-site (In-situ). Thus, option (A) is correct.
