includes a few hundred meters below the ground to several kilometers into the atmosphere
What is a habitat?
An area with the combination of resources (food, cover, water) and environmental conditions (e.g. temp., precip.) that promotes residency by individuals of a given species and allows them to survive and reproduce.

What is niche separation?
When two animals live in the same area but use different resources
What is an ecological equivalent?
When there is another species that fills basically the same niche in a different area
What is convergent evolution?
