Pollination is not a supporting service for water quality and availability. It is a regulating service that helps to ensure the reproduction of plants.

Soil formation contributes to water quality and availability by helping to filter pollutants from water, store water in the ground, and regulate the flow of water through ecosystems.

Nutrient cycling plays a vital role in water quality and availability by ensuring that plants have the nutrients they need to grow, preventing water pollution, and regulating the flow of water through ecosystems.

Climate regulation affects water quality and availability by regulating the amount of water that evaporates from the Earth's surface, the amount of water that falls as precipitation, and the temperature of water bodies.

Supporting services for water quality and availability are essential for human health and well-being, the survival of aquatic ecosystems, and the functioning of the global water cycle.
