Ecology Basics
The portion of Earth that Supports Life
What is the Biosphere
All non-living factors in an environment.
What is Abiotic (Factors)

What is Predation.
Each step in a food web or food chain.
What is a Trophic Level.
Energy _________ through an ecosystem while matter _______through.
What is "flows" and "cycles"
The scientific discipline in which the relationships among living organisms and the interaction the organisms have with their environments.
What is Ecology

What is the littoral Zone.
The orderly and predictable change that occurs after a community of organisms has been removed but the soil has remained intact.
What is Secondary Succession
