 Ecosystems are made up of living and non-living
  things.

 Ecosystems are interactions of living (biotic) and
  non-living (abiotic) components.

 Ecosystems are made out of producers, consumers
  and decomposers.

 Matter and energy are necessary for all ecosystems.

 Natural changes (e.g. weather) can cause changes in
  an ecosystem.

 Human activities can change ecosystems also (e.g.
  pollution, cutting down trees)

 Technologies have been developed to manage wastes
  that humans generate.
