Biology Module 5.02
Data and Observations:
Create a data table containing a tally of the number of each color of prey in each generation:

Data Analysis:
Create a graph that tracks the changes in the prey population’s colors.
Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report:
Reflection questions need to be answered using complete sentences. Some questions may require a longer explanation in paragraph form.
How do the original and surviving prey populations compare?
In the beginning there is the same number of population. Over time the lighter colored prey survived longer.
How did the colors of each type of prey affect its population size over time?
The prey that is lighter in color lasts longer. As time goes on, the white prey last longer than the blue colors as the blend into their surroundings better. The red, green and orange went almost extinct over the 3 generations because they could be spotted easier and could not blend into their surroundings.
What color(s) seemed to camouflage the best in this habitat? What color(s) seemed to stand out the most?
The white color seems last the longest as prey. The green color is the first to go as it is so bright they are easily seen.
How do you predict the data would change if you continued? Explain your answer.
The white and blue prey would be able to survive the longest and the red, orange and green would not be able to populate fast enough and could go extinct if protection of the animals were not put in place.
Predators eat the prey. When there are too many predators, the number of prey dwindles and the predators would then starve. When there are too many prey, the number of predators can increase quickly because a large number of the prey will be between the young and old and the sick and dying.
