Helpful Habitats

A habitat needs five basic requirments for an animal to survive. They are
1. Air
2. Space
3. Food
4. Water
5. Shelter
If one of these requirments is missing then
the living creature can not survive. Lots of things can change in the habitat
of a living creature but these things may be harmful or helpful.
