1.
Make a hypothesis about how you think the two species
of Paramecium will grow alone and how they will grow when they are grown
together. Paramecium
2.
Explain how you tested your hypothesis.
3.
On what day did the Paramecium caudatum population
reach the carrying capacity of the environment when it was grown alone? How do
you know?
4.
On what day did the Paramecium aurelia population reach
the carrying capacity of the environment? How do you know?
5.
Explain the differences in the population growth
patterns of the two Paramecium species. What does this tell you about how
Paramecium aurelia uses available resources?
6.
Describe what happened when the Paramecium populations
were mixed in the same test tube. Do the results support the principle of
competitive exclusion?
7.
Explain how this experiment demonstrates that no two
species can occupy the same niche.
