Data and Observations: Create a data table containing a tally of the number of each color of prey in each generation: Color 1. White 2. Blue 3. Red 4. _Orange_ 5. Green Generation O 20 Generation 1 56 4 Generation 2 Generation 3 32 Record any observations. 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 tot each type tot prey detect 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 lend 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. If there are too many prey, there will not be enough food for them all and the prey will starve, making themselves weaker and easier to kill. How would these results change if the colors or patterns of the habitat were to change?

If the colors changed and they were all light and able to blend better the prey may become over populated. Identify at least two things that are unrealistic and two things that are realistic about this exercise. The color of the prey may certainly help a prey blend in and seems realist, and eventually one type of prey may be easily picked out for one reason or another. The random picking up of squares seems unrealistic. Also the fact that the prey always has 3 babies seems unrealistic. What traits could help a predator be more “fit” in this model environment?

Being a combination of lighter colors could help the prey. Being quicker and smaller would help prey be able to get away. They would be able to adapt and stay hidden. On the other hand they could become over populated if they become too adept at fitting in. Describe other adaptations besides color that could affect an individual’s survival. Being able to see at night when fewer predators are out. Be able to stand cooler temperatures may help as there could be less predators in the area. Staying in a pack may help offer safety for larger animals.
