Which of the following is the broadest topic? Question 3 options:

The natural predators and prey of arachnids in tropical ecosystems

The natural predators of brown widow spiders in tropical ecosystems

The natural predators and prey of brown widow spiders in tropical ecosystems

I would think it would be the first one :)

"The natural predators and prey of arachnids in tropical ecosystems"

Explanation:
