During Hurricane Andrew, many Burmese pythons were set loose in the Florida Everglades. These snakes are considered an invasive species. How has the introduction of this species affected the populations in the everglades?
A. The other top predators, like alligators, will have the same amount of food to eat because the hurricane caused many other predators to die.
B. The native species will learn to adapt to the pythons over time. New species will move into the area and provide more food to the pythons and other predators.
C. The hurricane impacted many of the native species and caused predators to compete for food. The addition of the pythons will create problems for other predators and could cause prey species to go extinct.
D. The introduction of the python will not have an effect on the native species because the hurricane caused other predator populations to decrease. This allowed the number of predators to remain the same as it was before the hurricane.
C. The hurricane impacted many of the native species and caused predators to compete for food. The addition of the pythons will create problems for other predators and could cause prey species to go extinct.

How does soil biodiversity help to stabilize an ecosystem?
A. Low soil biodiversity leads to increased ability to recover from soil disruptions.
B. High diversity of soil organisms leads to increased nutrient recycling and more nutrients available to organisms.
