Biology UNIT 8

Carbon Cycle

What is the biochemical equation for Photosynthesis in words and symbols? Is energy being stored or released?

What is the biochemical equation for Cellular Respiration in words and symbols? Is energy being stored or released? 

Which organisms on earth are able to photosynthesize? Which organisms on earth are able to do cellular respiration?  of the above processes?  

Case Study: Boreal Forests: define a  “tipping point” using this case study as an example.

Be able to discuss each of these approaches to carbon sequestration: 

• Afforestation

• Forest Regeneration

• Restoration of peat-forming wetlands

How have atmospheric carbon dioxide concentrations changed over human history? 

How has data for changing CO2 concentrations been collected?

What is the difference between correlation and causation?

What evidence do we have that human (anthropogenic) effects have increased global temperature?

How is decrease in deep ocean upwelling a positive feedback cycle?

How is decrease in snow a positive feedback cycle?

How is decomposition of peat a positive feedback cycle?

How is melting permafrost a positive feedback cycle?

How are droughts positive feedback cycles?

How are forest fires positive feedback cycles?
