Question
What adaptation allows lichens to survive extended periods of drought and then rapidly become active when water is available?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Lichens can survive extended periods of drought, during which they become completely desiccated, and then rapidly become active once water is available again. This adaptation allows them to colonize hostile habitats such as rocks and tundra.
Hint
This survival strategy involves entering a dormant state when water is absent.
