I can... 

  • draw the flow of energy and a biochemical cycle 
  • insert in a biochemical cycle a food cycle 
  • indicate in the human body where you can find molecules that contain a lot of carbon, nitrogen or water
  • explain a scheme with the  carbon cycle and indicate producers, consumers and decomposers within.

misconcepts in the book
  • plants make their own food  glucose 
  • reducers decomposers 

Slide 4 - Slide

keypoints 
  • Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled.
  • The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.
  • Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Name molecules in your body that contains carbon and/or nitrogen

Slide 7 - Open question

The carbon cyle : key points 
  • Carbon is an essential element in the bodies of living organisms. It is also economically important to modern humans, in the form of fossil fuels.
  • Carbon dioxide - CO2 - from the atmosphere is taken up by photosynthetic organisms and used to make organic molecules, which travel through food chains. In the end, the carbon atoms are released as CO2 in respiration.
  • Slow geological processes, including the formation of sedimentary rock and fossil fuels, contribute to the carbon cycle over long timescales.
  • Some human activities, such as burning of fossil fuels and deforestation, increase atmospheric CO2 and affect Earth's climate and oceans.

Slide 8 - Slide

The carbon cycle
The carbon cycle is most easily studied as two interconnected subcycles:
  • One dealing with rapid carbon exchange among living organisms --> biological carbon cycle
  • One dealing with long-term cycling of carbon through geologic processes --> geological carbon cycle

Slide 10 - Slide

assigment 
  • indicate in the diagram 'producers', 'consumers', 'decomposers'
  • in this diagram you can replace a word with 'photosynthesis'. Which word / where? 
  • indicate the biological cycle and indicate the geological cycle
  • explain in your own words why climate change due to human activities would not take place in case the carbon cycle was only based on the biological carbon cycle.
