Question
A science class is studying a forested area near their school. They find English Ivy, a non-native species from Europe, is now an invasive weed with no natural predators. Data shows that the year after ivy first appeared in the forest, the native shrub population declined by half. When people removed the ivy, the native species returned slowly over a five year period. They claim that the best way to preserve biodiversity is to leave it alone and over time the forest will balance itself out to its natural state.

The two assumptions that this group has made that are contradicted by the data are:
**C. The native forest species may not compete well with invasive species.**
**E. Natural ecosystems will resist the effects of aggressively competitive species.**
These assumptions highlight the challenges native species face against invasive species and suggest that natural ecosystems might not rebalance on their own when confronted with such invasive threats. The data shows that removing the invasive species (ivy) allowed for the native species to slowly return, indicating that intervention can help restore biodiversity.
**C. The native forest species may not compete well with invasive species.**
**E. Natural ecosystems will resist the effects of aggressively competitive species.**
