Population Change
Directions: Listed below are this Learning Module lab questions to answer. When completed, upload this file back to the Lab dropbox (where you downloaded in the first place). FYI: I really like it when the answers are in a different format/color than the questions. It helps when grading.
Part 1. Population Biology is an online virtual lab that will illustrate how competition affects population growth. Follow the instructions given. Two species of unicellular organisms are used to determine patterns of population growth. Run the program to determine the growth pattern of each species.
a. Make a hypothesis about how you think the two species of Paramecium will grow separately. Then run the experiment. When the two species of Paramecium are separate both will survive as the days pass.
b. Keep track of your findings and then create graphs of your data using the provided tools. Take a screen shot of your graph, save as an image file, and upload for grading. You will have a screen shot for each paramecium grown alone for a total of 2 screen shots. Paste them below.
c. On what day did the Paramecium caudatum population reach the carrying capacity of the environment when it was grown alone? How do you know? Day 8 because the days after the same number was repeated.
d. On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know?
Day 14 because the day after, the same number was repeated.
e. Was your hypothesis correct? Why or why not?
Yes, because as the days passed both Parameciums increased as the days passed. I did not see any decrease on both.
f. Make a hypothesis about how you think the two species of Paramecium will grow when mixed together in the same test tube. I think when they are together only one will survive as the days pass.
g. Run the experiment with the two species combined. Create a graph of this portion of the experiment. Take a
