Lab 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. I think that they will grow the same amount alone but will double in size when grown together. 2- Explain how you tested your hypothesis. I put one of each species in the their specific test tube but combined both species in the final test tube. 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? on day 6 because the amounts almost doubled. 4- On what day did the Paramecium aurelia population reach the carrying capacity of the environment? How do you know? On day 8, the slide was full. 5-Explain the differences in the population growth patterns of the two Paramecium species. What does

Unformatted text preview: this tell you about how Paramecium aurelia uses available resources? The aurelia grew substantially faster every couple of days. It uses its resources more more then the caudatum. 6- Describe what happened when the Paramecium populations were mixed in the same test tube. Do the results support the principle of competitive exclusion? The species doubled in capacity and it continued to grow more every couple of days. 7- Explain how this experiment demonstrates that no two species can occupy the same niche. The amounts were different each day and they always increased. Carbon Footprint-25- estimated emissions comparison 27- US avg per person 5.5 world avg per person 25 tons of Carbon dioxide...
