A certain species of frog comes in two different colors, green and brown. A population of these frogs live in and along a river. In 1980, a very large drought occurred, causing most of the river to dry up. Most of the plant life around the river died as well. Why did the green frog population decrease after the drought?

The green frog's population decreases because they cannot blend as easily into the mostly brown environment of the dry river bed as their brown counter parts. There are not as many green plants for them to hide against, making it easier for predators to see them.
