The competitive exclusion principle states that one of the species would drive the other to extinction. When small, soft seeds become rare, large-billed finches will survive better, and there will be more larger-billed birds in the following generation; when large, hard seeds become rare, the opposite will occur. No, two species cannot live in the same ecosystem indefinitely. True or False (If false, replace the capitalized word to make the statement true.
