Which of the following statements about biodiversity is incorrect ?

Options

A. Number of species in tropics is greater than number of species in polar regions.
B. Number of species of vascular plants in a forest in Midwest USA is greater than the number of species of vascular plants in Equator.
C. Number of species in India is greater than number of species in Norway.
D. Number of bird species in Columbia is greater than number of bird species in New York .

Answer

To determine which statement about biodiversity is incorrect, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Concept of Biodiversity**:
Biodiversity refers to the variety of life in a particular habitat or ecosystem. It includes the number of species, genetic diversity, and the variety of ecosystems.

2. **Evaluate Each Statement**:
- **Statement 1**: "The number of species in tropics is greater than the number of species in the polar region."
- **Analysis**: This statement is correct. The tropics, particularly near the equator, have a higher number of species due to favorable climatic conditions, such as warmth and abundant sunlight, which support diverse ecosystems.

- **Statement 2**: "The number of species of vascular plants in the forest in Midwest USA is greater than the number of the species of vascular plants in the equator."
- **Analysis**: This statement is incorrect. The equator has a much higher diversity of vascular plants due to its warm climate and high levels of precipitation, which support lush forests.

- **Statement 3**: "The number of species in India is greater than the number of species in Norway."
- **Analysis**: This statement is correct. India, with its diverse ecosystems ranging from tropical forests to deserts, has a higher species count compared to Norway, which has a more temperate climate and fewer ecosystems.

- **Statement 4**: "The number of bird species in Colombia is greater than the number of bird species in New York."
- **Analysis**: This statement is also correct. Colombia is one of the most biodiverse countries in the world, particularly for birds, while New York has a significantly lower number of bird species.

3. **Identify the Incorrect Statement**:
From the analysis, the only incorrect statement is **Statement 2**, which claims that the number of vascular plant species in the Midwest USA is greater than that in the equator.

### Conclusion:
The incorrect statement about biodiversity is **Statement 2**: "The number of species of vascular plants in the forest in Midwest USA is greater than the number of the species of vascular plants in equator."
