What is an ecosystem?
200
Anything that restricts the number of individuals in a population is known as this.
What is a limiting factor?
200
The nonliving, physical features of the environment are called this.
What is an abiotic factor?
200
This is the model that describes how water moves from the surface of Earth to the atmosphere & back to the surface again.
What is the water cycle?
200
This is not recycled, but is converted from one form to another.

500
This abiotic factor is responsible for wind.
