2.3 Flows of Energy & Matter

2.3 Flows of Energy & Matter NOTES

Significant Ideas:

• Ecosystems are linked together by energy and matter flows.

• The Sun's energy drives these flows, and humans are impacting the flows of energy and matter both locally and globally.

Applications & Skills:

• Analyze quantitative models of flows and energy and matter..

• Construct a quantitative model of the flows of energy or matter for given data.

• Analyze the efficiency of energy transfers through a system.

• Calculate the values of both GPP and NPP from given data.

• Calculate the values of both GSP and NSP from given data.

• Discuss human impacts on energy flows, and on the carbon and nitrogen cycles.
