Read the following statements about biodiversity and state the one which is false.

Options

A. Western Ghats have a greater amphibian species diversity than the Eastern Ghats
B. India has a greater ecosystem diversity than a Scandinavian country like Norway
C. Among animals, insects are the most species-rich taxonomic group
D. New York has more bird species than Columbia

Answer

To determine which statement about biodiversity is false, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "The western Ghats have greater amphibian species diversity than the eastern Ghats."
- This statement is true as the western Ghats are known for their rich biodiversity, particularly in amphibians.

2. **Statement 2**: "India has greater ecosystem diversity than Scandinavian countries like Norway."
- This statement is also true. India has a variety of ecosystems including deserts, rainforests, mangroves, coral reefs, wetlands, and alpine meadows, whereas Norway has a more limited range of ecosystems.

3. **Statement 3**: "Among the animals, insects are the most species-rich taxonomic group."
- This statement is true. Insects, particularly within the phylum Arthropoda, make up a significant majority of animal species, with estimates suggesting that they account for about 70% of all described species.

4. **Statement 4**: "New York has more bird species than Colombia."
- This statement is false. Colombia, being closer to the equator, has a significantly higher number of bird species (approximately 1400) compared to New York, which has around 105 species. This follows the principle that biodiversity generally increases as one approaches the equator.

### Conclusion:
The false statement is: **"New York has more bird species than Colombia."** Therefore, the answer is option number 4.
