In spadefoot toads there are two forms of the tadpoles: omnivores and carnivores. Environmental factors such as population density, oxygen concentration, and availability of food determine which form any particular tadpole takes. Consider the situation below. A single pair of toads produces a fertilized group of eggs in a pond. The pond dries a bit creating two separate ponds, one is deep and the other is shallow. All the tadpoles in the deep pond become omnivores and all the tadpoles in the deep pond become carnivores. There is a heavy rain and the ponds become connected again and the two groups of tadpoles mix together. The carnivores eat most of the omnivores and more of the carnivores become adult toads This is an example of Group of answer choices A. natural selection and evolution B. evolution only C. natural selection only
