When presented with the question “Does Plant Food X have an effect on the production of tomatoes?” Develop a hypothesis to answer this question and then design a small controlled experiment to test the hypothesis.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

layer 3 is younger than layer 6.
