A team of scientists is studying three related species of thrushes, which are a type of bird. In all three species, the thrushes feed on insects and build nests in trees. The team uses a computer simulation to predict the populations of each species in a tract of forest, both with and without the presence of other thrush species. The results are shown in the table.Based on the computer simulations, which statement MOST likely describes an ecological relationship among the three species?(A) All three species compete for the same niche, and species B is the strongest competitor.(B) Species A and species C compete for the same niche, and species C is the stronger competitor.(C) Species B fills a different niche than either species A or species C.(D) Either species A or species C out-competes species B for its niche.
