Explanation:

The question is incomplete kindly find below the correct question.

In Australia, millions of nonnative cattle produce a huge amount of dung. For decades, Australia has imported nonnative dung beetles to help clean up the dung. Which sentence best explains why native Australian dung beetles were not doing the job?

A. Cow dung is not part of any native Australian species' niche.

B. Native Australian dung beetles lack a niche in Australia.

C. Cows have no known niche in Australia.

D. Decomposers lack a native niche in Australia.

B. Native Australian dung beetles lack a niche in Australia.

Explanation:

A niche is a place an organism occupies and the roll they play in an ecosystem. Because the dung beetles were nonnative and imported they have no niche in Australia compare to the Cow who have been settlers this makes it impossible for them to feed on the dungs because they are not use to the dung as source of feed and the dungs could not decompose because no activity was carried out on them.

This will make the cattle avoid feeding in the pasture due to accumulated dung but rather move far for pasture.

the answer is b: 1.4 km/hr
