UPSC 2012: The Millennium Ecosystem Assessment describes the following major categories of ecosystem services—provisioning, supporting, regulating, preserving and cultural. Which one of the following is a supporting service?
(a)Production of food and water
(b)Control of climate and disease
(c)Nutrient cycling and crop pollination
(d)Maintenance of diversity
Attempt This Question
Not attemptedCorrect Answer: (c) Nutrient cycling and crop pollination
Supporting services are underlying ecological functions such as nutrient cycling, soil formation and primary production that make all other ecosystem services possible. ‘Nutrient cycling’ (and by extension crop pollination that depends on it) is therefore classified as a supporting service, whereas food/water production is provisioning and climate control is regulating.
