You have been assigned to conduct a scientific study on the effects of four types of fertilizer on broccoli growth. You visit several broccoli farms to make observations and use these observations to find preliminary correlations and form hypotheses. To test your hypotheses, you set up five plots of broccoli - one plot for each fertilizer type plus a control plot, which is not fertilized. When you meet with your professor to discuss your progress, he tells you that your project is missing an important component of the scientific method. What is missing?
A. Testing biotic factors such as herbivore abundance B. Replicating each fertilizer treatment in multiple plots C. Using more than one plant species so your conclusions can be more broadly applied D. Testing the fertilizer in a natural setting on wild relatives of broccoli E. Setting up plots that receive more than one type of fertilizer
