Yes almost all ecosystems are dependent on plants creating sugars using the suns energy. Although it could be argued that ecosystems at the bottom of the ocean where small bacteria and underwater life exist and survive using the heat from underwater volcano vents, but then it could also be argued that they require the sun to exist and so then all ecosystems would be dependent on the sun.
