Nitrogen containing fertilizer are used by farmers to promote crop and plant growth. These fertilizers can runoff into various nearby water bodies. In a process called eutrophication, nitrogen dissolves in a body of water and stimulates the growth of plants and algae. When these plants and algae die, bacterial populations feeding on the dead material increase and consume a lot of oxygen in the water. Which of the following is likely to occur as a result of using nitrogen containing fertilizer?

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?
