Why did the white winged moth survived compared to dark-coloured moth before industrial revolution?
1 Thin growth of almost white-coloured lichen covered the trees
2 Thick growth of almost white-coloured lichen covered the trees
3 Thick growth of almost white-coloured mycorrhizae covered the trees
4 Thin growth of almost white-coloured mycorrhizae covered the trees
Explanation:
As the trees darkened with soot, the lightcoloured moths were easier to see. They were eaten by birds more and more, while the rare dark coloured moths blended in better on the darker trees.This made the dark coloured moths have a higher survival rate.
