In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of fish and four that were not. As they studied the ponds, they noted that the areas around the four fish-populated ponds showed decreased populations of dragonflies and dragonfly larvae, whereas the four without fish showed abnormally large populations of dragonflies and larvae. Dragonflies feed on bees, butterflies, and other pollinators.

Predict what would happen to the rate of pollination of flowers in a field next to a pond with no fish. Use evidence to support this prediction. Identify the keystone species in this scenario and explain how you have inferred this.
