The adaptations that allow thermophiles, a type of bacteria, to live within the hot springs of Yellowstone National Park include:
- the ability to live in a highly acidic environment
- the ability to withstand very hot temperatures
Thermophiles are specifically adapted to thrive in extreme heat, and many species can also tolerate acidic conditions, which are often present in hot spring environments. The other options listed (consuming insects and eating parasites) are not relevant adaptations for thermophiles.
