Ecosystems like fields are naturally patchy with respect to nutrients, meaning within a single field there are high, medium, and low nutrient patches. Arbuscular mycorrhizal fungi (AMF) species can be helpful for plants to gain nutrients especially in low nutrient patches. The addition of nutrients to a field through fertilization reduces the natural nutrient heterogeneity and creates consistently high levels of nutrients throughout the field. Biologists conducted a 5-year experiment to determine how the addition of fertilizer to a field every year affects AMF diversity. Which set of rank abundance curves below best represents the change in AMF diversity over the 5 year experiment due to the addition of fertilizer

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
