Read the given statements and select the correct option:
Statement 1: Pioneer community is the stable and final biotic community of an ecological succession.
Statement 2 : Pioneer community has maximum diversity and niche specialisation.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statement 1 and 2 are incorrect.

Explanation

To solve the question regarding the statements about the pioneer community in ecological succession, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding Ecological Succession**:
- Ecological succession is the process through which ecosystems change and develop over time. It involves different communities of organisms that replace one another in a specific sequence.

2. **Identifying Types of Communities**:
- There are three main types of communities in ecological succession:
- **Pioneer Community**: The first community that establishes itself in a previously uninhabited or disturbed area.
- **Seral Community**: Intermediate communities that develop after the pioneer community and before the climax community.
- **Climax Community**: The final, stable community that remains relatively unchanged until disrupted by an event.

3. **Analyzing Statement 1**:
- **Statement 1**: "Pioneer community is the stable and final biotic community of an ecological succession."
- This statement is incorrect because the pioneer community is not stable or final; it is the initial stage of succession. The climax community represents the stable and final stage of succession.

4. **Analyzing Statement 2**:
- **Statement 2**: "Pioneer community has maximum diversity and niche specialization."
- This statement is also incorrect. The pioneer community typically has low diversity and is characterized by niche generalization rather than specialization. Niche specialization develops in the climax community.

5. **Conclusion**:
- Both statements are incorrect. Therefore, the correct option is that both statement 1 and statement 2 are incorrect.

### Final Answer:
- The correct option is **D**: Both statement 1 and 2 are incorrect.
