is D cow dung is not part of any native australian species

Correct answer: D). Cow dung is not part of any native Australian species' niche

The beetles in Australia had formed along with the kangaroos and wombats. When the cattle are brought to Australia in the 1880. The beetles were not used to the texture of dung.

Because of this cattle were not able to feed the pasture because they were not be able to eat near the dung.
