Arrange the following in descending order of their percentage of the total cost of various ecosystem services

Options

A. Soil formation nutrient cycling gt climate regulation
B. Soil formation gt climate regulation gt nutrient cycling
C. climate regulation gt nutrient cycling gt Soil formation
D. climate regulation gt Soil formation gt nutrient cycling

Answer

To solve the problem of arranging the ecosystem services in descending order of their percentage of total cost, we will follow these steps:

### Step 1: Identify the Ecosystem Services and Their Percentages
We need to list the ecosystem services mentioned in the question along with their respective percentages:
- Soil Formation: 50%
- Nutrient Cycling: 10%
- Climate Regulation: 6%

### Step 2: Compare the Percentages
Next, we will compare the percentages of each ecosystem service to determine their order:
- Soil Formation has the highest percentage at 50%.
- Nutrient Cycling comes next at 10%.
- Climate Regulation has the lowest percentage at 6%.

### Step 3: Arrange in Descending Order
Now that we have compared the percentages, we can arrange them in descending order:
1. Soil Formation: 50%
2. Nutrient Cycling: 10%
3. Climate Regulation: 6%

### Final Arrangement
Thus, the final arrangement in descending order of their percentage of the total cost of various ecosystem services is:
1. Soil Formation
2. Nutrient Cycling
3. Climate Regulation
