Select the correct answer A. Contributions of services like recreation and nutrient cycling, are less than 10 percent each. B. The cost of climate regulation and soil formation are about 6 per cent each.
1 Only A is correct
2 Only B is correct
3 Both are correct
4 None are correct
Explanation:
Out of the total cost of various ecosystem services, the soil formation accounts for about 50 per cent, and contributions of other services like recreation and nutrient cycling, are less than 10 per cent each. The cost of climate regulation and habitat for wildlife are about 6 per cent each.

Ecosystem services are
1 Provide aesthetic, cultural and spiritual values
2 Generate fertile soils, provide wildlife habitat
3 Purify air and water
4 All of them
Explanation:
The products of ecosystem processes are named as ecosystem services, for example, healthy forest ecosystems purify air and water, mitigate droughts and floods, cycle nutrients, generate fertile soils, provide wildlife habitat, maintain biodiversity, pollinate crops, provide storage site for carbon and also provide aesthetic, cultural and spiritual values.
