"two species of salamander inhabit an island. the habitat on each side of the island is different. one side tends to be wet; the other side tends to be dry. researchers want to know if the salamanders will survive equally well on either side of the island. species a lives on the wet side of the island, while species b lives on the dry side of the island. researchers develop two artificial habitats, one that simulates conditions on the wet side and one that simulates conditions on the dry side.
explain why researchers would put the salamanders in an artificial environment, as opposed to conducting the experiment in their natural habitat"
