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

An invasive species, such as the trees in your question, could:

- Out compete the native flora for resources, such as nutrients.

- An earlier reproductive and faster growing cycle could quickly surpass native tree growth.

- This alien species taking the place of native trees could disrupt the habitat of animal species that need the native flora instead.
