1. Unit 08 Ecology: 11 Carbon Fluxes

2. Understandings and Applications
Carbon fluxes
4.3.A1 Estimation of carbon fluxes due to processes in the carbon cycle. [Carbon fluxes should be measured in gigatonnes.]
4.3.A2 Analysis of data from air monitoring stations to explain annual fluctuations.
Chi squred = 0.36

3. Ecology 11: Carbon Fluxes
Objectives
Warm Up
State one way CO2 is taken out of the atmosphere.
State 4 ways CO2 is cycled back into the atmosphere.
Describe why carbon fluxes occur throughout a year in an ecosystem.
Analyze atmospheric CO2 data

Chi squred = 0.36

7. Based on the previous slide, how would you define carbon flux?
Carbon flux: the transfer of carbon from one pool into another
Pool: a reserve of the element, can be inorganic or organic
Give examples of a pool of an inorganic pool of carbon and an organic pool of carbon.
Chi squred = 0.36

14. Wrap-Up What are carbon fluxes?
How does the atmospheric carbon dioxide change throughout a single year?
Describe the trend of atmospheric carbon dioxide levels from 1958 – 2014
Are there fluctuations within the overall trend?
