Many European larger banded snails live in forest habitats. Imagine that a forested area that provides habitat to some of these snails is impacted by a widespread fire that burns much of the
plant matter, leaving the area heavily covered by black ashes.
Place an X in one of the boxes provided next to the data line on the graph that correctly represents
the likely effect of the fire on the frequency of the light-colored shell trait in the snail population in
this area over time.
