thanks Materials 10 mL Vegetable Oil "Water Labware 10 mL Graduated Cylinder 100 mL Graduated Cylinder Note: You must provide the materials listed in red. EXPERIMENT 1: ECOLOGICAL INTERACTIONS In this experiment, you will demonstrate how substances accumulate in trophic levels through biomagnification PROCEDURE 9 mL of water into the 10 ml graduated cylinder. The graduated cylinder represents a primary producer. □ 2. Add 1 mL f oil to the 10 ml graduated cylinder containing the water. Note that the oil is insoluble in the water, and thus will accumulate in the water much like some substances accumulate in an organism's tissues 3. Record the volume of oil in the 10 mL graduated cylinder in Table 2. □4. Pour the oil and water mixture into the 100 mL graduated cylinder. Repeat 1,2 and 4 four more times. Wait until the water and oil has settled, then record the volume of oil in your 100 mL con- tainer in Table 2 5. ble 2: Volume and Concentration Totals Cylinder Volume of 1000 ml 100 ml Trophic Cylinder Oil 1st 2nd Post-Lab Questions 1. What does the water in this experiment represent? What does the oil represent? How did the amount of oil change from one trophic kevel to the next? 2. How does the change in the amount of oil relate to bionagnification? tion shows how energy is accumulated at a higher trophic level, as oil represents energy, the accumulation of the oil represents the energy accumulated 4. Why would this change in amount of an accumulating substance potentially be of concern in the food chain of an ecosystem?
