CHOOSE THE BEST ANSWER A recent study оf plаnt species diversity in fields wаs structured аs fоllоws. In an "experimental" field the researchers sprayed an insecticide to specifically remove a species of beetle that uses goldenrod (a species of plant) as its preferred food. In the "control" field the researchers did not spray the insecticide and therefore left that field in an unaltered condition. In the "experimental" field it was found that the goldenrod population density increased dramatically and eventually came to dominate the field and exclude other plant species. This change did not occur in the "control" field. Based on these results, it is reasonable for the researchers to propose that the beetle species is a...
CHOOSE THE BEST ANSWER The figure аbоve prоvides dаtа оn the population growth of two species of small aquatic crustaceans that occupy the same niche. Both species were grown separately (left graph and middle graph) and together (right graph) to assess their competitive interaction. What is the outcome of the two species competing, illustrated in the final graph on the right?
