An estimated 1 million bats have died from white nose syndrome ( wns). what is one environmental impact on the immediate ecosystem?

The dying out of one million bats because of the white nose syndrome will have multiple environmental impacts. The bats are predators of the insects, thus they control their numbers. Taking in consideration how fast of a metabolism the bats have, and how often they need to eat because of it, we can see that they have huge importance in controlling the numbers of the insects. Once the bats are gone though, the populations of insects will explode. This will cause destruction of lot of populations of plants. As the plants are destroyed, the ecosystem may totally crumble as the plants are the basis of it by being the producers and providing the primary food source for the majority of the animals. This can lead to to totally destroyed ecosystem which will need lot of time to recover.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
