Answer:

D. Ecosystem

Explanation:

The living beings and the non-living conditions of a region interact with each other. They together make an ecosystem. In the given study, the aim was to restore the above-ground vegetation of the region. The "above ground vegetation" of the region is part of its biotic factors. The "below ground soil" is a component of the abiotic factors of the region. Since the study focused on both biotic and abiotic factors of the region, it focused on the ecosystem.
