Example:The trees, rocks, and wildlife aroung a rabbit.
Interact
Definition:Living and nonliving things acting on eachother.
Example:Grass grows and rabbits eat it.
Physical Enviornment
Definition:Nonliving things in an enviornment.
Example:Water, Air, light, and climate.
Biological Enviornment
Definition:Living things in an enviornment.
Example:Plants, trees, animals.
Ecosystem
Definition:Made up of living and nonliving things in an enviornment that interact with eachother.
Example:Rabbits eat the grass.
-Eco
Definition:Enviornment.
Example:Forest.
-System
Definition:Set of parts that work together as a single unit.
Example:Populations

Example:Rabbits.
Community
Definition:All populations living together in an ecosystem.
Example:Rabbits, Foxes, Birds, Plants, etc.

Definition:Process by which one community is replaced by another over time.
Example:Lichens to eventually Maple Trees.
Climax Community
Definition:The final community that replaces a past one.
