Question

Study the following and pick the correct statements:

• A. A biogeographic region with a significant reservoir of biodiversity that is under threat of extinction from humans is called a biosphere reserve.
• B. Cryopreservation, in-vitro culture, gene banks, etc., are some methods of ex-situ conservation.
• C. Species diversity between two adjacent ecosystems is called beta (\(\beta\)) diversity.
• D. Digitalin is obtained from the Foxglove plant.

Hint:

Ex-situ conservation protects species by removing them from their natural habitat, while in-situ conservation protects them within their habitat.

Answer 1

The Correct Option is D

Step 1: Understanding Biodiversity and Conservation Terms
- Biosphere Reserve is a protected area for sustainable conservation, but it is not necessarily under threat.
- Ex-situ conservation methods include Cryopreservation, gene banks, and in-vitro culture.
- Beta (\(\beta\)) diversity is the difference in species diversity between two ecosystems, not adjacent ecosystems.
- Digitalin is a cardiac glycoside obtained from the Foxglove plant.
