Select all the services that grasslands provide.

Grasslands provide a variety of essential ecosystem services that support both environmental health and human activities. While building deep and rich soils is certainly a characteristic of healthy grassland ecosystems, the other options also reflect significant services provided by grasslands.

Grasslands do indeed help build deep and rich soils over time through the decomposition of organic matter from various plant species. This process enriches the soil with nutrients, making it suitable for diverse plant and animal life. The extensive root systems of grassland plants contribute to soil structure and prevent erosion, further enhancing soil fertility.

Additionally, grasslands play a crucial role in carbon sequestration, effectively storing carbon dioxide from the atmosphere. This feature helps mitigate climate change by reducing greenhouse gases.

Moreover, grasslands filter runoff from precipitation, improving water quality by trapping sediments and other pollutants. This filtration process is vital for maintaining healthy water systems.

Finally, grasslands also provide recreational opportunities, such as hunting, hiking, and birdwatching, which contribute to human enjoyment and appreciation of nature.

In conclusion, grasslands are multifaceted ecosystems offering a range of services vital for ecological balance and human well-being, making a comprehensive understanding of these functions essential in conservation and management practices.
