How does the destruction of forests contribute to levels of atmospheric carbon?

Answer

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.

Explanation

Trees absorb carbon dioxide from the atmosphere during photosynthesis. When forests are destroyed, fewer trees remain to absorb it, so less carbon dioxide is removed from the air. Therefore, the correct choice is “Fewer trees leads to smaller amounts of carbon dioxide being absorbed from the atmosphere.”
