Effect of oil spills on aquatic plants
The hydrilla plant in the beaker with a layer of oil stopped producing oxygen after 3 hours, while the plant in the beaker without the oil continued to produce oxygen even after 5 hours.
|Condition||Amount of oxygen produced by the hydrilla plant (mm)|
|1 hour||2 hour||3 hour||4 hour||5 hour|
The above results were than plotted onto a graph, as shown below.
