In figure 1.1 we can see the reusults for only the pillbugs in the light, hot, shelter, and moist chambers since the results showed these were their greater likings. In figure 1.2 we can see the light (COLOR), hot (), shelter (), and moist () results to see how many left that spot, came back and then stayed until the amounted time was up. Pillbugs seemed to be more attracted to the light and had an average number of 6 isopods, over 4 in the dark chamber. We see in figure 1.2 that pillbugs had a greater average in the hot, sheleter and moist chambers, with averages of 7 and
