What are 2 special adaptations that lichens have in the polar ice cap?

Lichens in the polar ice cap have developed special adaptations such as the ability to tolerate extreme cold and desiccation, allowing them to survive in harsh, frigid conditions. Additionally, they possess a unique photosynthetic strategy that allows them to utilize limited sunlight effectively during the short growing seasons, enabling them to thrive in nutrient-poor environments. These adaptations make them resilient pioneers in one of Earth's most extreme habitats.
