Rоundwоrms аre аble tо reproduce sexuаlly or asexually. The graph below shows the results of an experiment that compared sexual reproduction rates in roundworm populations exposed to three different bacteria treatments: roundworm populations that were never exposed to bacteria (dotted black line) roundworm populations that were periodically exposed to bacteria that were allowed to evolve (solid black line) roundworm populations there were periodically exposed to bacteria that were not allowed to evolve (highlighted in red). In Treatment 3, the rate of sexual reproduction increased, but then, after 8 generations, decreased. What is the most likely cause of this decrease in sexual reproduction?
