把段落排成正确顺序
1The American mink has been present in Iceland since the 1930's and despite heavy hunting since 1939 the species has become well established.
2Iceland is therefore an ideal place to study undisturbed feeding behaviour and ecology of mink.
3The ecosystem in Iceland is simpler than in other areas where mink are found; the only other mammalian predator is the arctic fox.
4Direct competition between these species appears to be minimal although the arctic fox will sometimes chase mink and disturb them while foraging.
