the natural predators of brown widow spiders in tropical ecosystems
the natural predators and prey of brown widow spiders in tropical ecosystems
narrower

Explanation:

Step1: Analyze the scope of each topic

• "the natural predators and prey of arachnids in tropical ecosystems" focuses on all arachnids in tropical ecosystems, covering a wide range of arachnid species.
• "the natural predators and prey of brown widow spiders in tropical ecosystems" focuses on a specific arachnid species (brown widow spiders) and includes both predators and prey.
• "the natural predators of brown widow spiders in tropical ecosystems" focuses on a specific arachnid species (brown widow spiders) but only on their predators, which is a narrower scope than including both predators and prey.

Step2: Order from broadest to narrowest

1. The broadest topic is about all arachnids: "the natural predators and prey of arachnids in tropical ecosystems"
2. Next, the topic about brown widow spiders with both predators and prey: "the natural predators and prey of brown widow spiders in tropical ecosystems"
3. The narrowest topic is about brown widow spiders' predators only: "the natural predators of brown widow spiders in tropical ecosystems"

Answer:

1. the natural predators and prey of arachnids in tropical ecosystems
2. the natural predators and prey of brown widow spiders in tropical ecosystems
3. the natural predators of brown widow spiders in tropical ecosystems
