The Barton Springs salamander lives only at the spring outflows of Barton Springs near Austin, Texas. They are often found under rocks or among gravel in water several inches to fifteen feet deep. They can also be found hiding in aquatic plants and algae. They rely on a clear, clean, continuous flow of spring water. They are known to eat amphipods (tiny aquatic crustaceans) and other small aquatic animals. The Barton Springs salamander is clearly capable of living underground, but also inhabits surface environments.

What is the MOST likely way that humans could have a damaging impact on the Barton Springs salamander?

Question 2 options:

Adding new water vegetation

Adding new crustaceans

Polluting the water

Floating down the river
