Use the data you calculated in parts A and B to explain why gypsy moths could threaten biodiversity in the ecosystem.


Answer: edmentum

The number of gypsy moths is growing exponentially in a short period of time, which suggests that there are few predators controlling their population. This growth also aids the exponential destruction of shrubs and trees, which native species rely on for food and shelter. Increased competition for these resources will likely cause the population of many native species to decline. Over time, some of the native species may die out or leave the area, leading to a decline in biodiversity.
