Concepts Explored: Trophic levels, food webs, biogeochemical cycles, human impact on biogeochemical cycles. Experiment: In this set of procedures you will measure mushroom yield under various conditions. You will study how levels of concentration of nitrate, heavy metals, and pH affect mushroom yield in separate experiments. This activity will require about two hours. Please log […]
