3.4 Carbon cycle

The ​ (a)   cycle is the basic building block of the carbohydrates, fats, proteins, DNA and all other ​ (b)   compounds required for life.

It is part of the ​ (c)   molecules produced through ​ (d)   and eaten or decomposed by ​ (e)   .

Over millions of years, the ​ (a)   in deeply buried marine deposits of​ (b)   were converted into carbon containing fossil fuels. The ​ (c)   of overlying sediments and heat released during the ​ (d)   of dead matter formed coal, oil, and natural gas (​ (e)   )

• carbon
• dead plant matter and algae
• high pressure from the weight
• decomposition
• fossil fuels

What about (a)   ? This forms in a similar way – organic matter accumulates in a place with little (b)   , is buried, ‘cooked’ and turned into a useful substance and store of energy. Coal forms from (c)   which is plant matter in wet places on land. Oil forms from organic matter that settled on the (d)   to form a substance called (e)   .

• oil
• Oxygen
• peat
• sea bed
• oil shale

If we removed too much ​ (a)   from the atmosphere, the primary effect would be a significant ​ (b)   , leading to a colder climate with potentially widespread impacts like increased ​ (c)   , reduced ​ (d)   , and disruptions to ecosystems due to the ​ (e)   , making Earth significantly colder and potentially inhospitable to life as we know it

• carbon dioxide
• drop in global temperature
• ice cover
• plant growth
• weakened greenhouse effect
