I chose a pie chart because its easy to see the comparisons between the number left of the dark and light lemon peppered moths and its also easier to see which type of moths had the biggest population. Using a pie chart would be the most understandable but if I were to use a line graph it wouldnt make sense because line graphs are used to show amounts over time
Question: How Does the change in forest color affect the population of the Lemon Peppered Moths.
Variables:
IV:Change In Forest Color
DV: Lemon Peppered Moth Population
Hypothesis: If there is a change in the white forest color then the population of the white lemon peppered moths will decrease because they would have to adapt to a new environment because its being eaten by predators because it cant camouflage in its new environment
Claim: If the white colored forest changes to a black colored forest then the population of the white lemon peppered moths will decrease because they will stand out more in the black colored forest so they will be spotted easier by predators. Since the white lemon peppered moths are being eaten more often the black peppered moths will thrive because they can camouflage into the black colored forest.
Evidence: As you can see the first chart is showing the percentages of the white and black moths left in the White colored forest. The percentage of the white moths left was 81 percent while the percentage of the dark colored moth was 19 percent. The white moths thrived in this environment because of their ability to camouflage, while the black moths will sooner or later die out because they cant camouflage in this environment so they are more vulnerable to predators. In the second chart, we see the same results except in the black colored forest. The percentage of black colored moths left is 54 percent and the percentage of the white colored moths left is 46%. The black colored moths thrived in the black colored forest because since it can camouflage in this environment it was harder for predators to spot so it wasn't as vulnerable, but on the other hand the white colored moths stood out in this environment because it cant camouflage so the white colored moths would also sooner or later die out. This lab modeled that an organism with a more beneficial trait will thrive in its environment and other traits will not.
How does this lab model Natural Selection?
This lab modeled natural selection because it showed us that an organism with a more beneficial trait will thrive in its environment. In the experiment we saw how the light colored moth thrived in the light colored forest because the moth blended into its surroundings so it wasn't caught by predators, meanwhile the black moths can't blend in in a environment that is all white, so the population of the dark colored moths increased because they were being eaten by predators. The white colored moths were also reproducing with more white colored moths since the population of the dark colored moths was decreasing. Eventually their wouldn't be anymore black colored moths in white colored forests because they are being eaten.
