In this book by Dr. Seuss, the Lorax looks on helplessly as the Onceler clan lays waste to the landscape by chopping down every last Truffula tree. The Onceler's made thneeds from the tufts of the Truffula trees. They were so caught up in the fat profits they were realizing from selling thneeds that they didn't notice that they were permanently destroying the place where they and their children lived. In this assignment you are to develop a spreadsheet modeling the sustainable production of thneeds from the Truffula forest growing from that one seed. The Truffula Forest A forest eco-system eventually achieves a stable cycle of birth, growth and death of trees.
Mature trees grow seeds that reach the ground and new seedlings grow.
Eventually, the existing trees die of old age or from natural disaster. The dead trees fall to the ground, decay and are reabsorbed into the soil as nutrients for the living trees. If a forest is not constrained by physical boundaries it will often spread. The first task in this assignment is to develop a spreadsheet modeling the natural cycle of the forest. The main item of interest is the number of trees in the forest, lets call this quantity the Population .
