300
Based on the food web what level of consumer is the lizard?

If temperatures rise in a certain ecosystem and cause a once snow covered environment to melt, what would happen to the white haired rabbits that populate that ecosystem?
They would not be adapted to the warm weather or to the brown/green landscape for protection from predators - therefore they would not survive and reproduce. - those that did survive (if any) would be rabbits with brown in their fur
