Options

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 solve the question regarding which statement is correct about biodiversity, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Evaluate Statement 1**:
- The statement claims that the medicinal plant *Rauvolfia vomitoria*, found in the Himalayan range, shows diversity in the synthesis of the chemical colchicine in higher concentrations.
- **Analysis**: This statement is incorrect because *Rauvolfia vomitoria* does not produce colchicine. Colchicine is actually derived from the plant *Colchicum autumnale*. Therefore, this statement is false.

2. **Evaluate Statement 2**:
- The statement suggests that the Eastern Ghats have greater species diversity of amphibians than the Western Ghats.
- **Analysis**: This statement is also incorrect. The Western Ghats are known for having a higher species diversity of amphibians compared to the Eastern Ghats. Thus, this statement is false.

3. **Evaluate Statement 3**:
- The statement claims that at the ecosystem level, India has greater ecosystem diversity than a Scandinavian country like Norway.
- **Analysis**: This statement is correct. India, located in tropical and subtropical regions, has a rich variety of ecosystems, while Norway, situated in the Arctic region, has a much lower diversity due to its colder climate. Therefore, this statement is true.

4. **Evaluate Statement 4**:
- The statement states that biodiversity is a term popularized by sociobiologist David Tilman.
- **Analysis**: This statement is incorrect. The term "biodiversity" was popularized by biologist Edward O. Wilson, not David Tilman. Hence, this statement is false.

### Conclusion:
After evaluating all four statements, the only correct statement regarding biodiversity is **Statement 3**: "At the ecosystem level, India has a greater ecosystem diversity than a Scandinavian country like Norway."

### Final Answer:
The correct statement regarding biodiversity is **Statement 3**.
