The ecosystem is the lowest level of the biosphere hierarchy to include
a.. the animal species present.
b.. weather patterns and soil conditions.
c.. interactions between different species.
d.. the plant species present

The ecosystem is the lowest level of the biosphere hierarchy to include weather patterns and soil conditions. in the whole biosphere hierarchy, ecosystem actually placed as the second highest (1 place below biosphere) But there are only 2 hierarchy that include weather and soils, and those hierarchies are biosphere and ecosystem. So technically the ecosystem will be the lowest in this matter
