What Best Describes the Relationship Between Cutting Down Forests and Changes

What best describes the relationship between cutting down forests and changes in atmospheric carbon dioxide levels?

A) Herbivore populations decline in the absence of forests and without their respiration less carbon dioxide is recycled to the atmosphere.
B) The carbon dioxide used by the plants for cellular respiration would all be released into the atmosphere at once.
C) Trees naturally die and decompose, but when turned into lumber their carbon is prevented from recycling back to the atmosphere.
D) In the absence of forest plants there would be less carbon dioxide removed from the atmosphere for use during photosynthesis.
