In ponds where there are southern toads, eastern spadefoot toads, and spring peeper toads they all eat the same food source. When red-spotted newts are also present in the ponds, they preferentially eat the tadpoles of southern toads and eastern spadefoot toads.

A)Their fundamental niche expands. B)Their realized niche expands. C)Their ecological niche stays the same.
