Based on the results, when both species were grown alone, they decreased in population after they reached carrying capacity, P. caudatum starting earlier than P. aurelia. This shows that they both thrive when there is no competition, but soon start dying off. When they were put in mixed cultures, the P. aurelia took advantage of the rice and quickly grew in population, but P. caudatum couldn’t compete with the other species and soon died off. This shows that P. aurelia is strong in competition but P. caudatum is weak. The hypothesis was that when both species are alone, that their population will be about the same, but when mixed, one species will dominate the other. This hypothesis is rejected because although one species dominated the other
