An invasive species is an organism that's not native to a particular ecosystem but ends up invading the region. The
populations of invasive species can rise sharply, in part because the species may not have natural predators to
control their populations.
The graph shows the population of an invasive tree species spreading through a region. This tree has an earlier
reproduction and growing season than many of the native trees. Give three examples of how this tree could affect
competition with the native species of plants and animals in the forest.
