Carbon cycle

What are nutrients?

chemicals required for growth and other life processes

What does the amount of nutrients flowing =

amount of nutrients flowing out (balanced)

What are nutrients?

chemicals required for growth and other life processes

What does the amount of nutrients flowing =

amount of nutrients flowing out (balanced)

What are carbon atoms?

fundamental units in a cell of all living things

How can carbon be stored?

• short term storage:

  • aquatic and terrestrial organisms

  • C02 in the atmosphere

  • top later of the ocean

• long term storage:

  • coal, oil and gas deposits in land and ocean sediemnts

What are the five chemical elements required for life?

Carbon. hydrogen, oxygen, and nitrogen cycle between living things and the atmosphere. Phosphorus cucles in the form of sedimentary rock.

What’s the carbon cycle?

• Carbon dioxide gas moves from the atmosphere into the biosphere through photosynthesis and cellular respiration

• Carbon dioxide also moves back to the atmosphere when organisms die and decompose

• Carbon enters the geosphere when the remains of organisms are trapped under sediment layers

What’s global warming?

An increase in the average temperature of eatrh’s surface

What is global climate change?

a long term change in earth’s climate

What are the effects of excess carbon in the carbon cycle: rising sea level and changing ocean chemistry?

• Rising sea level

  • some islands have gone underwater

  • sale water gets into drinking water supply

  • coastal flooding and destruction of wetlands

• changing ocean chemistry

  • ocean becomes more acidic because it absorbs more Carbon Dioxide

  • an acidic and warming ocean can destroy coral reefs
