Unformatted text preview: nutrient levels were most likely insufficient for the number of living duckweeds. 4. If we observed the culture for an additional two weeks we would probably find that the duckweeds in culture 2 had reach the carrying capacity and may have even started to die. Culture 1 with a total of 7 duckweeds would probably double in number if the nutrients were sufficient. 5. Another factor that we could test for the duckweed population could be the size of the cultures that we used. We could see if a larger culture would allow the duckweeds to keep growing. Using this method, we could formulate a chart to show the carrying capacity compared to a certain amount of water. Ex: The carrying capacity for 200 ml of pond water is 58. Then we could try to manipulate the growth rate by adding nutrients and changing the abiotic factors....
