Options

A. Primary succession is a slow process
B. Climax community is always mesic
C. Members of climax community are competitive
D. Members of poineer community are local

Answer

To solve the question "Select an incorrect statement," we will analyze each of the four given options one by one to determine which statement is incorrect.

### Step-by-Step Solution:

1. **Analyze the First Option:**
- The statement is: "The primary succession is a slow process."
- **Evaluation:** This statement is true. Primary succession occurs in lifeless areas where soil has not yet formed, such as bare rock. It is indeed a slow process as it takes a long time for organisms to colonize and for soil to develop.

2. **Analyze the Second Option:**
- The statement is: "The climax community is always magic."
- **Evaluation:** This statement is also true. Climax communities are stable and mature ecosystems that have reached a steady state, often found in specific conditions such as wet areas, which can be referred to as "magic" conditions.

3. **Analyze the Third Option:**
- The statement is: "The members of the climax community are always competitive."
- **Evaluation:** This statement is incorrect. Members of a climax community are typically stable and have reached a balance with their environment, which means they are not necessarily competitive. Instead, they coexist and maintain stability within the ecosystem.

4. **Analyze the Fourth Option:**
- The statement is: "The members of the pioneer community are local."
- **Evaluation:** This statement is true. Pioneer species are the first organisms to colonize previously uninhabited areas and are often local species that can survive in harsh conditions.

### Conclusion:
After evaluating all four options, the incorrect statement is:
- **Option 3:** "The members of the climax community are always competitive."

### Final Answer:
The correct answer is **Option 3**.
