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)   .

What is the key component of the carbon cycle?

What process removes carbon dioxide from the air?

The cells of oxygen consuming producers, consumers and decomposers carry out

Use the diagram to answer question:

What is the only way that carbon is taken out of the atmosphere?

Use the diagram to answer the question:

How do plants and animals put Carbon dioxide back into the air

On the land, which organisms release carbon stored in the soil back into the atmosphere?

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)   )

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
