1. A scientist observes a pond located adiacent to a golf course and observes a thick mat of algae covering approximately half of the surface. The banks of the pond allow rain and snowmelt to enter the pond from the golf course property and there are emergent plants such as cattails growing around the perimeter. The scientist decides to run sev- eral water-quality tests to gather data. The results appear in the table to the right. (a) Based on the data shown, design an experiment that tests the relationship of a factor directly related to the growth of the algae. Dissolved ox- pH Nitrate Phosphate Total chlo (1) State a hypothesis that will test the possible cause of the algal bloom. (ii) Describe the procedure that will test the hypothesis. (iii) Identify the control in the experiment. (iv) Identify the dependent variable. (v) Discuss the expected results of this experiment. (b) There are many causes of cultural eutrophication. (i) Identify TWO possible sources of cultural eutrophication. (ii) Describe the sequence of events that takes place during this process, ultimately r species in a pond or lake. (c) Organisms that live in estuaries (marine wetlands) are well adapted to rapidly changing em (i) Identify and describe TWO characteristics of estuaries to which organisms must (ii) Identify ONE economic benefit of estuaries.
