Explain why tropical rain forests are not good farming locations even though they have high net primary productivity

The soil of tropical rainforests tends to be acidic and low in minerals and nutrients and this is because the dead organic matter coming from the tropical vegetation gets recycled very rapidly before it can become part of the soil so the actual soil remains devoid of nutrients.

Aproximately 5 pieces can be cut from it.

See diagram.we use washers to get the area and we will be integrating with respect to xouter radius is the  distance between y = e^x and y = -1    inner radius of washer is the distance between y = 1 and y = -1    the area of one cross-section of a washer is    solid lies between x = 0 and x = 2. the volume is    if you need this expanded, then    the question doesn't say to evaluate, so we're done.
