Which of the following statement is correct regarding biodiversity ?

Options

A. Medicinal plant Rauwolfia vomitoria growing in the Himalayan range show diversity in the synthesis of chemical colchicine in higher concentration and potential .
B. Eastern Ghat have greater species diversity of amphibians than Western ghat.
C. At the ecosystem level, India , has greater ecosystem diversity than a Scandivavian country like Norway.
D. Biodiversity is the term popularised by the sociobiologist David Tilman.

Answer

To determine which statement is correct regarding biodiversity, let's analyze each option step by step:

### Step 1: Analyze Statement 1
**Statement:** Medicinal plant Rauwolfia vomitoria growing in the Himalayan range shows diversity in the synthesis of chemical colchicine in higher concentration and potential.

**Analysis:**
- Rauwolfia vomitoria is known for its medicinal properties, particularly in treating hypertension and mental disorders. However, it does not produce colchicine. Colchicine is produced by a different plant, Colchicum autumnale. Therefore, this statement is incorrect.

### Step 2: Analyze Statement 2
**Statement:** Eastern Ghats have greater species diversity of amphibians than the Western Ghats.

**Analysis:**
- The Western Ghats are known for their rich biodiversity, especially in amphibians. In contrast, the Eastern Ghats do not have the same level of species diversity. Therefore, this statement is also incorrect.

### Step 3: Analyze Statement 3
**Statement:** At the ecosystem level, India has greater ecosystem diversity than a Scandinavian country like Norway.

**Analysis:**
- India, being located in the tropical and subtropical regions, has a wide range of ecosystems due to its varied climate and geography. Norway, on the other hand, is predominantly in the Arctic region, which has limited biodiversity due to its cold climate. Thus, this statement is correct.

### Step 4: Analyze Statement 4
**Statement:** Biodiversity is the term popularized by sociobiologist David Tillman.

**Analysis:**
- The term "biodiversity" was popularized by Edward Wilson, not David Tillman. Therefore, this statement is incorrect.

### Conclusion
After analyzing all the statements, the only correct statement regarding biodiversity is:

**Correct Answer:** Statement 3 - At the ecosystem level, India has greater ecosystem diversity than a Scandinavian country like Norway.
