On what day did the Paramecium caudatum population reach the carrying capacity of the environment when it was grown alone? How do you know?
1. What are the objectives for this experiment?
Demonstrate how competition for natural resources in the environment can 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.
Alone I think that they’ll grow quicker than together because there would be more competition for food and
3. Explain how you tested your hypothesis.
Well I figure if the paramecium are together then they would have competition for food. So if they are alone then they all could share the food that way they can all have energy.
4.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 10 because after coounting them over and over it was the same number everytime.
5 On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know?
Day 4 because after day four they begin to die off. whikle the others still prevails.
6 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?
when both use resources then one is probably more suitable for the food and the other one has to fight for the food in order to survivie so I think that one is going to die off and the other is going to still remain alive and keep going. Or the food might have chemicals that kill one but not the other.
7. Describe what happened when the Paramecium populations were mixed in the same test tube. Do the results support the principle of competitive exclusion? (you may need to briefly explain what competitive exclusion is
8 When the paramecium populations were mixed one of then slowly began to decrease while the other reached carrying cappacit and grew kicking the other paramecium out of the picture.
9.Explain how this experiment demonstrates that no two species can occupy the same niche.
Two species can’t occupy the same niche becasue there is always going to be some kind of competiton with the two. ]
