What does the root distribution within the prairie ecosystem cause?

t he fertile soil underground
food for bacteria and organisms
the variety of grass species
All of the above are correct

All of the above are correct. The root distribution within the prairie ecosystem plays a crucial role in nutrient cycling and soil fertility. The roots break down and release nutrients into the soil, making it fertile and suitable for plant growth. Additionally, these roots provide food for bacteria and other organisms that help decompose organic matter and facilitate nutrient cycling. Finally, the diversity and density of roots contribute to the variety of grass species that can thrive in the prairie ecosystem.
