Birds on Christmas Island all live in the same habitat but they prey on fish of different sizes and feed in different places.
Thus, each species occupies a distinct (different) ____________.

• community
• niche
• resource
• population

The prairie dogs demonstrating an example of:

• tolerance range
• biological niche
• intraspecific competition
• interspecific  competition

When put together, one organism outcompetes the other for resources.  This is an example of:

• competitive exclusion principle
• speciation
• biological niche
• evolution
