Read the following scenario and answer the question below.
Human activities, including fossil fuel combustion, farming, and deforestation, are known to increase the levels of carbon dioxide, methane, and nitrous oxides in our atmosphere. Measurable warming of Earth due to these greenhouse gases can alter ecosystem dynamics. In addition to the direct climatic effects on organisms within biomes, warming can lower levels of sea ice and increase precipitation in arctic areas. Global warming also can increases sea surface temperatures, which can subsequently melt permafrost in the tundra and increase the intensity of hurricanes in vulnerable areas. Within communities, climatic change can shift interdependent species ʺout-of-sync,ʺ potentially causing indirect loss of species.
-Of the following, ______________ might be first to populate an area after permafrost melts in response to global climate change.
A) grasses
B) shrubs
C) lichens
D) hardwood trees
E) aspen trees

Lichens are often among the first organisms to colonize areas where permafrost has melted due to their ability to survive in harsh, nutrient-poor environments and their role in soil formation, which is crucial for the subsequent establishment of other plant species.
