Eutrophication


Introduction

Nutrients is given to crops in farms and the nutrients then runs off into the ocean.


Methods

We used two cups of soil 1,800 ml of water, we also used two aponogeton plants. We measured the water with the beaker of 150ml 12 times and for the soil we used a measuring cup of Ÿ we also used two fish bowls. The experiment lasted 10 days but we only recorded 7 days. For the control group we didn’t give it anything it was just in water and planted in dirt. For the experimental group we did the same as the control, but we put in 50 ml of nutrients each day.

Results Our experiment showed us multiple outcomes that we didn’t know of. The experiment showed no growth and shunk due to the overdose of nutrients. At the start of the experiment the experimental plant was at 20 cm and the control plant was at 18 cm. Throughout the experiment we kept adding the nutrients to the experimental group after a while when tracking the data we noticed that they started to stop growing and started shrinking. At the end of the experiment the control group went from 18-15 cm. The experimental group went from 20 cm-13 cm. The control group there was a 535% decrease in height. In the experimental group there was a 17% decrease in height for the experiment.

Discussion How does Eutrophication affect the plants in the sea? The hypothesis was if there was extra nutrients in the sea then the plants will get the nutrients and start to grow in height and population. We weren’t able to see if our hypothesis was right due to the experimental group’s plant dying in the process due to having too much nutrients and the control group didn’t die it survived longer but dried up. What we did find out was that its exactly what Eutrophication was.
