Key Idea A self sustaining ecosystem requires the continuous cycling of matter, achieved through three functional groups: Producers (energy capture), Consumers (energy transfer), and Decomposers (matter recycling).
Section 1
Ingredients for Sustainability
A self-sustaining ecosystem requires the continuous cycling of matter, achieved through three functional groups: Producers (energy capture), Consumers (energy transfer), and Decomposers (matter recycling).
The removal of any single group breaks the cycle. Sustainability depends on the interaction of all three groups to ensure that atoms are reused indefinitely.
Section 2
Closing the Loop
Decomposers act as atmospheric regulators. By breaking down waste, they ensure a steady release of carbon dioxide, maintaining the atmospheric composition needed for plant life.
This regulation closes the carbon loop. It allows photosynthesis to continue over the long term, securing the stability of the entire ecosystem.
