D. The cost of climate regulation and habitat for wildlife are about 6 percent together.

Answer

To solve the question, we need to analyze each statement provided and identify the incorrect one. Here’s a step-by-step breakdown:

### Step 1: Analyze the Statements
1. **Statement 1**: "Ecosystem services have been given a price tag of 33 trillion US dollars per year."
- This statement is correct. The value of ecosystem services has indeed been estimated at around 33 trillion dollars annually.

2. **Statement 2**: "Dense forests reduce the chances of natural disasters."
- This statement is also correct. Dense forests can mitigate the impact of natural disasters by stabilizing soil, reducing flooding, and providing barriers against wind.

3. **Statement 3**: "Floods or droughts mitigate natural calamities."
- This statement is incorrect. Floods and droughts do not mitigate natural calamities; rather, they are themselves natural calamities that can cause significant damage.

4. **Statement 4**: "Nutrient cycling occurs due to forest ecosystems."
- This statement is correct. Forest ecosystems play a crucial role in nutrient cycling, which is essential for maintaining soil fertility and ecosystem health.

5. **Statement 5**: "Pollination of crops becomes easier because the organisms that pollinate are a part of the biological community of the forest."
- This statement is correct. Forest ecosystems support a variety of pollinators that contribute to the pollination of crops.

### Step 2: Identify the Incorrect Statement
From the analysis, we see that Statement 3 is incorrect because floods and droughts do not mitigate natural calamities; they are destructive events themselves.

### Conclusion
The incorrect statement is:
**"Floods or droughts mitigate natural calamities."**
