What do all these games have in common?
They are all about an animal's niche: it's place in nature relative to other animals.
If you're not sure what this means, go back and play any of these games again.

Scientists have learned what happens when different animals live together in the wild. Most of the time all the animals' niches make up all the jobs that get done in that place, like in the Help Wanted game.
The games in level two take a closer look at some of the ways that different animals interact with each other.

Sometimes, two animals that have the same niche try to live in the same place. When this happens, they compete for the things that both want. Click on "Winners and Losers" to find out about some head-to-head contests.
