Ecosystem Ecology: Energy



NOTE!!! By the end of this class you should be able to discuss what is WRONG with the diagram shown above!!!!!


Ecosystem ecologists focus on the flow of energy and the cycling of nutrients through the ecosystem.  In this lesson we will focus on energy.

Further Readings

Ecosystems- http://www.eoearth.org/article/Ecosystem

Ecological energetics- http://www.eoearth.org/article/Ecological_energetics

Expected Learning Outcomes

By the end of this course a fully engaged student should be able to

- diagram and discuss the flow of energy through an ecosystem

- discuss the implications of the energy pyramid on the population sizes and risks of extinction.

- discuss why the "inverted trophic pyramid" originally described in coral reefs was so disturbing to ecologists.
