Choose how many of the given statement are not correct about the Tropics ?
(i) Greater species diversity compared to Temperate
(ii) Subjected to frequent glaciations in the past
(iii) Great seasonal variations are seen here
(iv) Enviornment is relatively constant

Options

A. One
B. Two
C. Three
D. Four

Explanation

To determine how many of the given statements about the tropics are not correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "Greater species diversity compared to Temperate"
- **Analysis**: This statement is correct. The tropics are known for having a higher species diversity compared to temperate regions due to the greater amount of solar energy received, which leads to higher productivity and biodiversity.

2. **Statement (ii)**: "Subjected to frequent glaciations in the past"
- **Analysis**: This statement is incorrect. The tropics were not subjected to frequent glaciations in the past. Instead, temperate regions experienced glaciation during the ice ages, while tropical regions remained relatively undisturbed, allowing for the accumulation of diverse species.

3. **Statement (iii)**: "Great seasonal variations are seen here"
- **Analysis**: This statement is also incorrect. The tropics experience less seasonal variation compared to temperate regions. The environment in the tropics is relatively constant, which supports a stable ecosystem and high species richness.

4. **Statement (iv)**: "Environment is relatively constant"
- **Analysis**: This statement is correct. The tropical environment is characterized by relatively constant conditions, which is conducive to the specialization of species and contributes to high biodiversity.

### Conclusion:
Based on the analysis:
- Incorrect statements: (ii) and (iii)
- Therefore, **2 statements are not correct about the tropics**.

### Final Answer:
The number of statements that are not correct about the tropics is **2**.
