Why is soil considered to be a detritus-based ecosystem? Describe how the aboveground portion and the belowground portion of an ecosystem act as two interrelated, interdependent communities
What will be an ideal response?
Soil is a detritus-based ecosystem because the source of energy for the ecosystem is detritus. The aboveground portion of an ecosystem provides the detritus (energy and nutrients) for the belowground ecosystem, and the belowground ecosystem breaks down the detritus into a form that can be taken up by plants in the aboveground portion. Each ecosystem is dependent upon the other.
