The enviorment that they were introduced to is most likely free of predators to that species...which means that fewer are eaten, more offspring survive, etc.

There are none of the natural predators or competitors to slow the new species expansion. There is variability in this as well, depending on the invasive species and the habitat it is first released in.

because they are alien to the habitat, there are little or no predators that are specialized to keep the population in check. whatever the organism finds to feed on may also not be prepared to resist them, as it has not encountered the species ever before. this can also mean that there will be very little competition for food, as the invasive species starts in relatively low numbers and has an advantage over native species.

Usually because the invading species has been removed from it's own natural predators.

Because in this new place they usually do not have their natural predator or parasites specializing in them to control their numbers.
