Phosphorus Pollution in a Lake

Introduction:

This model shows how much contaminants go into the lake from the factory. We are calculating the amount of phosphorus in six organisms such as water, phytoplankton, zooplankton, fish, detritus and sediment. You are to put the numbers below to see how much phosphorus will go into the lake. Then, the graph will be made in order to show you.
