Affiliate Marketing Secrets

Hopefully in your animal science class, you learned that every animal has it’s own niche, or job in the animal kingdom. They make discovery channel shows about how hard their niche/life is. Out of all the existing ones, which one do you think has it the hardest. In my opinion, would probably be the ant.
Here’s why:
Everyone trying to kill it(Even other ants).
It has to lift things more than ten times it’s size.
It spends it’s entire life traveling one block.
It’s trying to dig it’s home, but it’s soon destroyed by 5-year old kids.
They have to gather food for the leader ant and not themselves.
We’re about a million times bigger than it.
Now that you know my opinion, what’s yours. Don’t say people’s life is the hardest because our life is easy compared to most animals.

I have homework for my science class but I can’t seem to find anything on the internet about a river otters niche. Can you help?
