|1. What are the objectives for this experiment? (you can summarize) |
|To analyze how competition for resources and limited resources affect population growth. |
|2. 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. |
| P. aurelia grows faster alone but almost at the same rate when mixed with the caudatum. The P. caudatum grows relatively slower and will eventually die out in |
|competition with aurelia. |
|3. Explain how you tested your hypothesis. |
|I based my hypothesis on the observed growth chart where you can see an exponential (log) increase in the early stages(days 1-6) and a lag at days 8-16. |
|Comparing this figure with the same P. aurelia grown in the mixed culture will have relatively the same number of population. For P. caudatum, the growth is at |
|a slower rate as compared to the P. aurelia. In the mixed culture, we can see that due to competition, the caudatum will eventually die out of lack of food |
|(since it was indicated that both are non-predator species).
