The most complex level of organizational hierarchy in the arctic national wildlife refuge that is preserved is?

This reserve is home to terrestrial and marine mammals, including grizzly and polar bears, caribou, wolves, and wolverine as well as beluga and bowhead whales, walrus, and several species of seals. It was established for the purpose of preserving unique wildlife, wilderness, and recreational values.

The most complex level of organizational hierarchy in the Arctic National Wildlife Refuge that is preserved is every ecosystem in the area.
