How does deforestation affect the carbon cycle?

• It increases the amount of carbon dioxide absorbed by plants.

• It decreases the amount of carbon stored in the biosphere.

• It has no significant effect on the carbon cycle.

• It increases the amount of carbon in the geosphere.

In the context of the carbon cycle, what role does the geosphere play?

• It is the primary source of carbon dioxide through volcanic activity.

• It acts mainly as a carbon sink through the formation of fossil fuels and sedimentary rocks.

• It releases carbon dioxide into the atmosphere through photosynthesis.

• It has no significant role in the carbon cycle.
