• the air

• all of these

The entire point of a carbon sink is

• it emits no carbon

• it absorbs no carbon

• it emits more carbon than it absorbs

• it absorbs more carbon than it emits

How does deforestation contribute to change in atmospheric carbon?

• Levels of atmospheric carbon are unaffected by destruction of forests, because the carbon entering the carbon cycle from the dead trees balances out the loss of carbon absorption during photosynthesis.

• When trees are destroyed, their stored carbon reenters the carbon cycle decreasing levels of atmospheric carbon.

• Fewer trees leads to greater amounts of carbon dioxide being absorbed from the atmosphere.

• Fewer trees leads to smaller amounts of carbon dioxide being absorbed from the atmosphere.

Trees play an essential role in the removal of carbon from the environment; Trees use carbon dioxide when growing.
