In an ecosystem snakes eat salamanders, and salamanders eat earthworms. how would the ecosystem be affected if a large number of snakes are caught and moved out of the region as a part of a conservation program?

If snakes are taken away, the salamander population will grow way higher than it should since there's nothing eating them. Therefore, earthworms would most likely have a decreasing population as all those salamanders need to eat. eventually, the earthworm population will become very small, the salamander population also because there's not enough food for all of them to eat.
