Question

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.

Answer 1

The early reproduction and growing season indicates that these trees will sprout sooner than many native trees. Because all trees need space to grow, the invasive tree species can reduce available space for native species to grow.

•As the trees grow, they could limit sunlight availability for other species of trees and plants in the area.

•Some plant-eating animals may rely specifically on native tree species for food. If the invading tree species reduces the supply of the native tree species, competition among the animals may increase.
