1 Ecosystems

2 Ecosystem All of the living and non-living factors interacting together in an environment.

3 Components of an Ecosystem
Abiotic Factors (non-living) Biotic Factors (living) Producers Consumers Decomposers

4 Processes of an Ecosystem
Biochemical Cycles Carbon Dioxide-Oxygen Cycle Nitrogen Cycle The Water Cycle Energy Flow (nutrient cycle) Community Dynamics

5 Changes in an Ecosystem
Environmental Natural changes such as floods, fires, droughts, and shifts in temperature Competition Occurs when species must compete over limited resources Human Impact Use of natural resources, deforestation, pollution Challenge Yourself! ms/changes-ecosystems.htm
