Population Pyramids
The population expanded rapidly at the beginning, but has steady out recently. I think that there are more people now than before because we have found new ways to support more people.

This photo shows how the average temperature has gone up in the eastern states such as California and has gotten closer to the average temperature in the central states.
Species Diversity Lab
Postlab Questions—Write out and answer the following questions
1. Identify the parking lot that was the most diverse. Based on your observations during the lab, explain why your
prediction in question #1 of the prelab was supported or not supported.
I came to a conclusion that the student parking lot is more diverse. My observation was supported because their are more students from different house holds so some have
2. List the single most abundant species in each set of data, and write a plausible explanation to explain why these are
the most abundant species.
3. Determine the maximum and minimum values for the Shannon Diversity Index in the parking lot you surveyed.
4. If you conducted this lab in a shopping mall parking lot, predict whether the Shannon Diversity Index would be high or
low, and how it would compare to the school parking lots.
5. If you conducted this lab at a new car dealership, predict whether the Shannon Diversity Index would be high or low, and how it would compare to the school parking lots.

Wooly Worm Lab
A. The degree of freedom was six.
C. The chi-square is 79.23
D. There is a significant not random chance of selection.
E. The positive selection is subjected to the ones that are brighter colored because they stand out and are easier to be see by predator. The negative selection is better for the more natural colors of worms because it camouflages them into the area around them.
F. The colorful worms population will start to decrease and the natural colored ones will start to have a bigger population.
G. If you use feeding habits and color vision the ones who can see in color would be more likely to find the brighter colored worms. The feeding habits would come into effect based on times of day and based on what type of day it is.
H. If the community did not change there would be a lot more of the natural colored worms than there would be of the bright colored ones.
