Answer 1

The change that would create a new ecosystem is **an introduced species**. Introducing a new species can significantly alter the dynamics of the existing ecosystem, potentially leading to the establishment of a new ecological balance and community structure.

While a dam flooding a valley could also lead to changes and the development of a different ecosystem, the introduction of a species is a more direct and definitive action that creates shifts in interactions among species and the environment.
