1.3 Energy & Equilibria

1.3 Energy & Equilibria NOTES

Significant Ideas:

• The laws of thermodynamics govern the flow of energy in a system and the ability to do work.

• Systems can exist in alternative stable states or as equilibria between which there are tipping points

• Destabilizing positive feedback mechanisms will drive systems toward these tipping points, whereas stabilizing negative feedback mechanisms will resist such changes.

Applications & Skills:

• Explain the implications of the laws of thermodynamics to ecological systems.

• Discuss the resilience in a variety of ecosystems.

• Evaluate the possible consequences of tipping points.
