22. What do healthy ecosystems do: moderate climate renew air, water and soil cycle nutrients provide energy resources moderate climate renew air, water and soil cycle nutrients provide energy resources

23. Ecosystems Con’t: provide food and shelter slow soil erosion, prevent flooding natural population control provide biodiversity provide food and shelter slow soil erosion, prevent flooding natural population control provide biodiversity
