This experiment will determine the number of growth of each cell. . ?ae a hypothesis about how you thin the two species of Paramecium will grow alone and how they will grow when they are grown together.  -If they reproduce alone, the species multiply while if the species grow together, it takes lesser number to reproduce.  %. @plain how you tested your hypothesis. - Ive tested my hypothesis by counting the number of species on slide every other day. As they reproduce alone, their population increases but Ive notice that if they reproduce  together it lowers the number of the species they reproduce.  &. n what day did the Paramecium caudatum  population reach the carrying capacity of the en2ironment when it was grown alone= How do you now= -The P. !audatum reached the carrying capacity on the th  day because It grows the population up to the #$ cells on that day.  #. n what day did the Paramecium aurelia  population reach the carrying capacity of the en2ironment= How do you now=  -The P. Aurelia reached the carrying capacity on the %$, %&,%'th day. The population grows to its maximum at %$$ and remained constant on %$-%' th  day. 5. @plain the differences in the population growth patterns of the two Paramecium species. ;hat does this tell you about how Paramecium aurelia uses a2ailable resources=  -The growth P. Aurelia reproduced faster than the P. !audatum because it occupies a bigger space compare to the P. !audatum. And it is also has the bigger amount of resources than the P. !audatum.  !. 9escribe what happened when the Paramecium populations were mied in the same test tube. 9othe results support the principle of competiti2e eclusion= (you may need to briefly eplain what competiti2e eclusion is*  - The growth or the population of the two paramecium in the same test tube has an impact when mixed can be concluding in the principle of competitive exclusion. As they reproduce together in the same test tube, the population of the P. !audatum getting lesser compare to the P. Aurelia because it gathers the higher amount of nutrients or resources. And this is where the principle of competitive exclusion is happening.   . @plain how this eperiment demonstrates that no two species can occupy the same niche.  - (ust like in real life of competition, there is always a winner and always have the loser. )o, as we observed the species here in this experiment, we obviously know that the P. Aurelia can be concluding as the winner and the P. !audatum is the loser, because it cant reproduce together with another species. P. !audatum is easier to reproduce if its alone because there  is no competition happening in reproducing.
