SCIENTIFIC INQUIRYINTERPRET THE DATA The feather moss Pleurozium schreberiharbors species of symbiotic nitrogen-fixing bacteria.Scientists studying this moss in northern forests found thatthe percentage of the ground surface “covered” by the mossincreased from about 5% in forests that burned 35 to 41 yearsago to about 70% in forests that burned 170 or more years ago.From mosses growing in these forests, they also obtained thefollowing data on nitrogen fixation: Age(years after fire) N fixation rate[kg N/(ha · yr)] 35 0.001 41 0.005 78 0.08 101 0.3 124 0.9 170 2.0 220 1.3 244 2.1 270 1.6 300 3.0 355 2.3
Mycorrhizal fungi live in the soil and interact with the roots of plants. Essentail nutrients (e.g. nitrogenous compounds) are taken from the soil by the fungi and transferred to the plant roots. The fungi extract carbohydrates from the plant roots. What type of interaction is occurring? Group of answer choices commensalism predation competition mutualism

. SCIENTIFIC INQUIRY You are testing the hypothesis thatincreased population density of a particular plant speciesincreases the rate at which a pathogenic fungus infectsthe plant. Because the fungus causes visible scars on theleaves, you can easily determine whether a plant is infected.Design an experiment to test your hypothesis. Describe yourexperimental and control groups, how you would collect data,and what results you would see if your hypothesis is correct.
