The grаph shоws the pоpulаtiоn sizes reаched by a population of flowering plants and a population of flies when they are raised alone and when they are raised together. " The vertical axis is labeled ""Population Size"" and the horizontal axis shows three categories: ""Flowers alone,"" ""Flies alone,"" and ""Flowers and flies together."" A legend in the upper left indicates that black bars represent flowers and light gray bars represent flies. Under the ""Flowers alone"" condition, there is one black bar showing a small population size for flowers. Under the ""Flies alone"" condition, there is one light gray bar showing a medium population size for flies. Under the ""Flowers and flies together"" condition, there are two bars side by side: a black bar showing a large population size for flowers and a light gray bar showing a slightly larger population size for flies. The bars in the ""Flowers and flies together"" category are both taller than the bars in the single species conditions, with the fly population reaching the highest point on the graph." Given this information, what is the best description of the relationship between the flowers and the flies?
